Abstract:
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.
Biography:
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.
