Sensing/Imaging Faculty Candidate Seminar: "Thin-film Materials for Next-Generation Optoelectronics" by Dr. Kyle Renshaw 5.26.15/11:00am-12:00pm/ CREOL RM 103

Sensing/Imaging Faculty Candidate Seminar: "Thin-film Materials for Next-Generation Optoelectronics" by Dr. Kyle Renshaw
Tuesday, May 26, 2015 11:00 AM to 12:00 PM
CREOL Room 103

Celebrating the International Year of Light 2015

Dr. Kyle Renshaw

The conventional semiconductors that enable modern optoelectronics are limited in their applications due to their specific set of materials properties. The next generation of devices will be based on thin-film optoelectronic materials such as organic molecules, metal-oxides, graphene, and thin-films of conventional inorganic semiconductors. Thin-film materials offer new optical, electrical and mechanical properties that can be used develop devices with radically different architectures and functionality. Over the last three decades, these materials have been developed to enable inexpensive, large area, non-planar, flexible and/or transparent devices. This first consumer application of these materials recently arrived as large area organic LED displays in cell phones and televisions.
This talk will introduce basic properties of some archetypal thin-film materials and will highlight why these materials are well-suited for the next generation of optoelectronic devices. We will discuss the physical processes involved in photodetection and solar energy harvesting using these materials; next we identify the primary challenges that must be overcome to realize high-performance devices. Examples of broadband sensors, novel imagers and organic photovoltaics will be provided.

Since 2013, Dr. Kyle Renshaw has been a physicist in the Advanced Technology Center of the Electronic Systems division of Northrop Grumman Corp. located in Rolling Meadows, IL. He is an optoelectronics specialist with interest and experience in: 1) photodetection from the ultraviolet to the long-wave infrared, 2) image system characterization and modelling, 3) image processing and tracking, 4) novel semiconductor fabrication techniques, and 5) thin-film device design, fabrication, characterization and modelling. He received a B.S. in Engineering Physics from Cornell University in 2007. His M.S. in Electrical Engineering was conferred in 2012 and Ph.D. in Applied Physics was conferred in 2014 - both from the University of Michigan.
