Abstract
Since the invention of the twisted nematic (TN) field-effect in 1970, the nematic liquid crystal display technology which is based on electric field-effects has made remarkable progress. Field-effects are characterized by polarization sensitive macroscopic molecular liquid crystal configurations with electrically tunable optical appearance. 
The unique electro-optical building block concept of field-effect LCDs enables the integration and individual optimization of anisotropic optical thin-films and silicon electronics in LCDs. The remarkable progress made over the past 45 years, renders today virtually all applications of the communication between man and machine possible. They range from reflective LCDs with “zero power” consumption, such as digital watch LCDs, or remotely controlled electronic price tags in Shopping centers, to iPhones and large size, ultra-high resolution 4k television LCDs. Since the beginnings in 1970 this development has been spurred by interdisciplinary R&D between physics, material sciences, synthetic chemistry, semiconductor electronics, and engineering. It includes TN-LCDs (1970), super-twisted nematic (STN)-LCDs (1980s), thin-film transistor (TFT)-addressed TN-LCDs for computer monitors in the early 1990s and beyond, and multi-domain LCD configurations. The latter became possible in the late 1990s either by electric fringe-field electrode geometries, or by photo-alignment/patterning of LC molecules. Further enhanced contrast, large angles of view and shorter response times were the result. Moreover, spin-offs into potential future types of field-effect LCDs, such as polymer stabilized blue phase LCDs and ferroelectric LCDs became possible. 
This development is reviewed with examples of the multidisciplinary R&D of the author and collaborators on electro-optical field-effects, liquid crystal materials and polarized optical alignment and alignment patterning of monomeric and polymeric liquid crystal molecules in LCDs and optical thin-films based on liquid crystal polymers.

Biography
Dr. Martin Schadt was born on 16th August 1938 in Liestal, Switzerland. After having gained practical experience as electrician Martin Schadt majored in experimental physics at the University of Basel, Switzerland, where he received his PhD in 1967. He was granted a two year post-doctoral fellowship at the National Research Council, Ottawa, Canada, where he continued his research on the electronic and optical properties of organic semiconductors. In 1969 he and D.F Williams patented the first solid state, organic light emitting display (OLED).  Dr. Schadt’s first professional association was with the watch company Omega, where he investigated atomic beam standards. In 1970 he joined the Central Research Laboratories of F. Hoffmann-La Roche Ltd., Basel. Except for two years in biophysics, his research focused on the development of electro-optical field-effects based on liquid crystals and on liquid crystal materials. 1970 Dr. Helfrich and Dr. Schadt invented the twisted nematic (TN)-effect at F. Hoffmann-La Roche. The Roche TN-field-effect patent was granted in 20 countries and was licensed world-wide to the emerging field-effect LCD industry by Roche. The invention initiated a paradigm change towards flat panel field-effect liquid crystal displays (LCDs) enabling today’s LCD industry. The search for correlations between molecular structures, material properties and display performance, which Dr. Schadt started in the early 1970s, enabled the development of new liquid crystals for TN- and subsequent field-effect applications. As a consequence the pharmaceutical company Roche established itself as a major liquid crystal materials supplier for the emerging LCD-industry. Apart from his pioneering work on OLEDs, the TN-effect and liquid crystal materials, Dr. Schadt and collaborators invented the linear photo-polymerization (LPP) technology in 1991 enabling alignment of liquid crystal molecules by light instead of mechanically. This opened up novel LCD configurations and LCD operating modes, as well as numerous anisotropic optical polymer thin-films. 
Until 1994 Dr. Schadt headed the Liquid Crystal Research Division of Roche. Based on its photo-alignment technology the Division was turned in 1994 into the spin-off company ROLIC Ltd, an interdisciplinary Research and Development Company which Dr. Schadt built-up and headed as CEO and delegate of the Board of Directors until his retirement from the operating business in October 2002. He is now active as a scientific advisor to research organisations and continues research in collaboration with partner companies as an independent inventor. He is inventor or co-inventor of 166 patent families filed in Europe (EP) and holds more than 119 US patents. He has published 191 papers in leading scientific journals, including chapters in 6 books. Dr. Schadt became a Fellow of the Society Information Display (SID) in 1992 and a Fellow of the European Academy of Sciences in 2011. He is inventor or co-inventor of 166 patent families filed in Europe (EP) and holds more than 119 US patents. He has published 193 scientific papers in leading scientific journals, has given more than 150 lectures and contributed to 6 books. He has received the following Awards: the Roche Research and Development Award (1987), a Special Recognition Award and a Best SID Paper Award (1987), the SID Karl Ferdinand Braun Award (1992). Together with W. Helfrich, he received the Aachener und Münchener Preis für Technik und angewandte Naturwissenschaften (1994) and the Robert-Wichard-Pohl Prize of the German Physical Society (1996). Together with W. Helfrich and James Fergason, he received the IEEE Jun-ichi Nishizawa Medal (2008). In 2009 he received the Eduard Rhein Technoloy Prize. The G.W. Gray Medal of the British Liquid Crystal Society and the Blaise Pascal Medal for Material Sciences of the European Academy of Sciences (2010). The Frederiks Medal, highest recognition award of the Russian Liquid Crystal Society (2011). The Charles Stark Draper Prize of the US National Academy of Sciences (known as the “Engineering Nobel Prize”) together with G. Heilmeier, W. Helfrich and P. Brody (2012). European Inventor Award 2013 for Lifetime Achievement (2013). Fellow of US National Academy of Inventors NAI (2013). Honorary Prof. of Sichuan University, Chengdu (2013). Honorary Prof. of Nanjing University, Nanjing (2013).

ABSTRACT:
Low dimensional nanomaterials (1 D nanowires and 0 D quantum dots) represent important nanoscale building blocks with substantial potential for exploring new device concepts and materials for nanoelectronics, optoelectronics and energy technology applications. Three examples will be presented.  First, I will discuss my discovery of unique rectified silver/amorphous silicon/crystalline silicon (Ag/a-Si/c-Si) crossbar resistive random access memory (RRAM) effect in c-Si/a-Si core/shell nanowires and provide a comprehensive comparison between nanowire based and planar silicon based Ag/a-Si/c-Si RRAMs. The history of how this accidental nanowire based discovery solved a decades-long sneak current problem in RRAM field and eventually evolved into a game changing mainstream flash memory successor, Crossbar Memory, will be presented. Then I will report the experimental realization of high efficiency single coaxial group III-nitride heterostructured nanowire photovoltaic devices and light emitting devices. Meanwhile, a universal van der Waals epitaxial growth strategy for compound semiconductor nanowire arrays will be discussed. The vision of how the combination of nanowire array growth and heterostructured nanowire devices could possibly change the substrate limited status of III-Nitride research fields will be outlined. Lastly, I will present how quantum dots materials innovation and novel device structure design/processing helped resolve one long standing issue for organic based light emitting devices, the efficiency roll off at high driving current density. As a result, record breaking ultrabright, highly efficient, low roll off inverted red quantum dot light emitting devices (QLEDs) have been achieved (165,000Cd/m2 at <6v attack="" be="" discussed="" driving="" end.="" in="" instability="" issue="" long="" of="" only="" p="" qleds="" remaining="" strategies="" term="" the="" to="" voltage="" will="">

Seminar: "A Taxonomy of the Magneto-Optical Responses of Cyclic Plasmon-Supporting Metal Oligomers" by David J. Masiello 11.6.14/ 11:00am-12:00pm/ CREOL 103

Seminar: "A Taxonomy of the Magneto-Optical Responses of Cyclic Plasmon-Supporting Metal Oligomers" by David J. Masiello
Thursday, November 6, 2014 11:00 AM to 12:00 PM
CREOL Room 103

David J. Masiello, Assistant Professor
Department of Chemistry, University of Washington

Abstract:
The optical-frequency magnetic and electric properties of cyclic plasmon-supporting metal nanoparticle oligomers are explored through a combination of scanning transmission electron microscopy (STEM)/electron energy-loss spectroscopy (EELS) simulation and first-principles theory. A tight-binding type model is introduced to explore the rich hybridization physics in these plasmonic systems and tested with full-wave numerical electrodynamics simulations of the STEM electron probe. Building from a microscopic electric model, connection is made at the macroscopic level between the hybridization of localized magnetic moments into delocalized magnetic plasmons of controllable magnetic order and the mixing of atomic p_z orbitals into delocalized pi molecular orbitals of varying nodal structure spanning the molecule. It is found that the STEM electrons are uniquely capable of exciting all of the different hybridized eigenmodes of the nanoparticle assembly---including multipolar closed-loop ferromagnetic and antiferromagnetic plasmons, giant electric dipole resonances, and radial breathing modes---by raster scanning the beam to the appropriate position. Comparison to plane-wave light scattering and cathodoluminescence (CL) spectroscopy is made. The presented work provides a unified understanding of the complete plasmon eigenstructure of such oligomer systems as well as of the excitation conditions necessary to probe each mode.

Biography:
David J. Masiello completed a B.S. degree in mathematics from the University of Florida in 1999.  He then joined the University of Florida's Quantum Theory Project as a graduate student in chemical physics, where, in 2004, he received the Ph.D. degree working under the tutelage of Professor Yngve Öhrn.  His dissertation work explored a nonperturbative treatment of the interaction between molecules and the electromagnetic field, accounting for the redistribution of energy not only between different internal molecular degrees of freedom but also for its liberation to the dynamical electromagnetic field.  He then took two postdoctoral positions, one with Prof. William P. Reinhardt at the University of Washington (2004-2006) and the second with Professor George C. Schatz at Northwestern University (2006-2009).  Subsequently, David was hired back to the University of Washington in 2010 where he is now an assistant professor in theoretical chemistry.  Currently, Professor Masiello's research focuses on the theoretical understanding of a variety of nanoscale light-matter interactions involving the excitation of surface plasmon resonances.  Examples include electron energy-loss spectroscopy, cathodoluminescence, thermo-plasmonics, plasmon-enhanced catalysis, and plasmon-enhanced linear and nonlinear molecular optical phenomena.  As of Spring 2014, David is also a faculty member by courtesy in the Physics and Applied Mathematics departments at UW.

TOMORROW! Seminar: "Recent advances in LIBS instrumentation: Application in quantification and elemental imaging" by Vincent Motto-Ros 9.26.14/ 11:00am-12:00pm/ CREOL Rm 103

Seminar: "Recent advances in LIBS instrumentation: Application in quantification and elemental imaging" by Vincent Motto-Ros
Friday, September 26, 2014 11:00 AM to 12:00 PM
CREOL Room 103

Abstract
Laser-Induced Breakdown Spectroscopy (LIBS) is recognized as a promising technique which enables elemental analysis of any type of material. It is extremely versatile with high potential in term of applications, offering standoff analysis capability, requiring only simple sample preparation, and providing fast and real-time analysis. However, improving the repeatability and the reproducibility of LIBS measurements is still the challenging issue faced by the technique to fit the requirements of precise and accurate quantitative analysis.
In the first part of this presentation, I will describe a new generation of LIBS instrument developed in our institute. The basic instrumental concept is to assist, either manually or automatically, the optical detection fiber by a real-time imaging of the plasma. This tends to improve greatly the stability of LIBS measurement in short as well in long terms [1], allowing unprecedented level of performances in elemental quantification (c.f. fig. 1a.). In the second part, some of our recent results will be presented in the frame of elemental imaging of biological tissue. We will show different examples of elemental images, sections of tumors and murine kidneys, with an investigation focused on the renal clearance of theranostic gadolinium-based nanoparticles (Fig. 1b.). The efficiency of LIBS imaging allows elements being mapped and quantified in tissues without any labeling and with an instrumentation fully compatible with standard optical microscope systems, offering a valuable tools in the fields of nanotechnology, biology, as well as medicine. [2].
