[Patterson, Robin L.]

Please join us for the Physics Colloquium today, at 3:45 PM in The Robert Smith Seminar Room. There will be a reception at 3:30PM in the Atrium. Details concerning the talk are as follows:

Speaker:         David Cobden (University of Washington)
Date:               Tuesday, April 9, 2019
Time:              3:45PM
Place:             1080 Physics Research Building, The Robert Smith Seminar Room
Title:                The Mysteries of a Two-dimensional Semimetal

Abstract:  Graphene is an example of a two-dimensional (2D) semimetal. It shows incredibly diverse and intriguing behavior, especially when multiple graphene sheets are stacked in various ways. We have been studying another 2D semimetal, WTe2, which has much stronger spin-orbit interaction and lower symmetry than graphene. It too show diverse behavior, including the quantum spin Hall effect, gate-induced superconductivity, ferroelectricity, and more which we are only beginning to explore. Some wonderful features of 2D materials are that they can be electrically gated, coupled easily to each other, and interrogated with powerful surface probes. I will describe how we are exploiting these features to try to better understand the rich physics of WTe2 and of 2D semimetals in general.
