About the author: Thayer Walmsley earned his Ph.D. in Physics in August 2021 under the direction of Dr. Yaqiong Xu. He is currently a J.D. student at Vanderbilt Law School. His Ph.D. work focused on exploring novel two-dimensional materials and their applications via scanning photocurrent microscopy. In his recently published work, he fabricated 2D metal-semimetal junctions using a gold transfer technique and the charge density wave material Titanium Di-selenide. Temperature dependent photocurrent studies on these devices revealed an abrupt change in photo-response speed associated with the CDW phase transition. This work probes the interplay between photons and electrons in exotic materials providing insight into engineering temperature-dependent, two-dimensional, fast optoelectronic devices.
