Abstract: The ability to extract key parameters of semiconductor materials such as bandgaps, carrier lifetimes, and noise coefficients is instrumental to developing the next generation of electronic and photonic devices. Ideally, semiconductor characterization techniques are sensitive, nondestructive, and universally applicable to different material systems. Thus, there has been a resurgence in contactless material characterization using microwaves to interact with and read out semiconductor properties. While traditionally effective for large, bulk-scale crystals, the significant length-scale mismatch between microwaves (centimeters) and modern thin-films of optoelectronic materials (micrometers) results in poor microwave-matter interaction, negatively impacting the sensitivity of the approach. In response to this challenge, I will present contactless microwave-based techniques which exploit exotic materials and resonant structures for microwave field confinement, improving the overall microwave-matter interaction. I will discuss the impact of confining microwaves on contactless semiconductor material characterization methods and describe the future of the field.

Dr. Sukrith Dev
Sukrith Dev is currently an Assistant Professor in the Electrical & Computer Engineering department at The University of Alabama in Huntsville (UAH). He received his B.S. and M.S. degrees from the University of Illinois Urbana-Champaign in 2015 and 2016, respectively, and he earned his Ph. D. from The University of Texas at Austin in 2019, all in electrical engineering. During his
Ph. D., he was a Department of Defense SMART Fellow and a recipient of The Ben Streetman Prize in Electronics & Photonics. Prior to joining UAH, Dr. Dev worked at the Air Force Research Laboratory (AFRL), where he served as either the principal investigator or co-investigator for several basic research efforts. His research earned him the Department of War Outstanding Civilian Award in addition to the Laboratory Scientist of the Quarter award. Currently, Dr. Dev is the founder and principal investigator of the MASER Lab at UAH, which conducts research in microwave photonics, quantum sensing, microwave-based material metrology, and millimeter wave devices.
