Abstract:

Graphene, which is an atomically thin layer of graphite, was first isolated in 2004 by a research group at the University of Manchester. The discovery initiated a massive research effort into 2-dimensional materials, which have the potential to enable significant improvements in fields like high speed electronics, flexible electronics, transparent conductors, biological sensors, and others. Key to enabling future technology is understanding the physical properties and growth processes of the 2-dimensional materials. Graphene, for instance, can be grown by a variety of different techniques. Sublimation of Si from SiC and chemical vapor deposition on Cu are two such growth techniques, both of which are promising due to their ability to be scaled up to a manufacturing environment. In this talk, I will introduce some of the techniques used by surface scientists as they apply to my research studying the physical properties of the 2-dimensional material graphene. As time allows, I will also discuss some more recent work on materials relevant for neuromorphic computing, including a new optical spectroscopy instrument that we developed for measuring optical properties in ultra-high vacuum.

Biography:

Zachary Robinson is currently an Associate Professor in the Physics Department at SUNY Brockport. His experimental work as a surface science includes developing a better understanding of synthesis techniques for 2D materials and neuromorphic computing materials. Zachary also studies the relatively new deposition technique Atomic Layer Epitaxy for synthesis of ultra-thin crystalline films. He was a postdoctoral fellow in Chip Eddy’s group at the Naval Research Laboratory from 2012 – 2015, and continues collaborating closely with colleagues from NRL. Zachary did his graduate work in the surface science lab of Dr. Carl Ventrice at SUNY Albany (now SUNY Polytechnic). He has a B.S. in Physics from SUNY Geneseo.
