Prof. David Egolf and a team of three former Georgetown undergraduates, Edward Banigan (C'07), Matthew Illich (C'11), and Derick Stace-Naughton (C'11), have had their research featured on the cover of the prestigious journal Nature Physics. They uncovered dynamical mechanisms behind the intriguing phenomenon of granular "jamming", in which free-flowing grains (sand, oranges, pharmaceuticals, etc.) develop into a disordered, solid-like state when the density is high enough.
Semiconducting molybdenum disulfphide is an attractive material for novel
nanoscale optoelectronic devices primarily due to its inherently large
direct bandgap. However, a major technological hurdle has been the
inability to create solid-state hole transport in MoS2 transistors. A
recent breakthrough achieved by members of the Physics Department will
appear in Nature – Scientific Reports, entitled “Electron-hole transport
and photovoltaic effect in gated MoS2 Schottky junctions”. The author
list includes a diverse group – a visiting engineering professor from
The Department of Physics is pleased to announce the creation of the Walter Mayer Summer Undergraduate Research Fellowship. This new fellowship has been established through the generous support of Dr. David Auth (G'69), a former graduate student of the late Professor Walter Mayer. The first recipient of the fellowship is Alexander Zajac (C'15). Alex will spend this summer working with Professor Amy Liu on a research project to study superconductivity in chemically-doped single-layer MoS2.
Two Georgetown undergraduates will be giving talks about their research projects at the American Physical Society March Meeting in Baltimore next week. The March Meeting is the largest physics meeting in the world and over 8500 physicists are expected to attend this year. On Tuesday, sophomore John Kerin will be presenting a talk titled "Nonlinear dynamical analysis of fibrillation". In collaboration with Georgetown graduate Dr. Justin Sporrer (C'03) and Prof. David Egolf, John has been using techniques from the field of chaos to study cardiac fibrillation.
