Dr. Robinson obtained his B.S. degree in Physics with minors in Chemistry and Mathematics from Towson University in 2001. He received his doctorate degree from The Pennsylvania State University in Materials Science and Engineering in 2005. From there, he joined the Naval Research Laboratory in Washington D.C. as an NRC Post Doctorate Fellow where he developed highly carbon nanotube devices for detection of explosives and nerve agents. In 2007, Dr. Robinson joined the Penn State Electro-Optics Center as a research associate in the Materials Division and most recently (2012) joined the Penn State Materials Science and Engineering Department as an Assistant Professor. In 2013, he co-founded the Center for Two-Dimensional and Layered Materials, and currently serves as Associate Director of the Center. Most recently he He has authored or co-authored over 80 peer reviewed journal publications with a significant focus on low dimensional electronic materials. He has patents on chemical and neutron detection, and his recent awards include the NSF-CAREER (2015), The G. Montgomery and Marion Hall Mitchell Award for Innovative Teaching (2015), Student Choice MatSE Faculty of the Year (2014), Penn State Miller Faculty Fellowship (2013), Oakridge Young Faculty Award (2013), Corning Faculty Fellowship (2013), Rustum and Della Roy Innovation in Materials Award (2012), Alan Berman Research Publication Award (2007), and a National Research Council Postdoctoral Fellowship (2005).
The last decade has seen nearly exponential growth in the science and technology of two-dimensional materials. Beyond graphene, there are a variety of layered materials that provide a broad range of electronic characteristics useful for transistors, flexible electronics, sensors, and photodetectors, to name a few. However, bridging the gap between science and technology often lies in one’s ability to synthesize materials on the wafer scale (or bigger). In this talk, I will discuss recent breakthroughs for direct growth of two-dimensional atomic layers and heterostructures with scalable techniques such as metal-organic chemical vapor deposition. We have demonstrated the direct growth of MoS2, WSe2, MoS2/WSe2, and hBN on epitaxial graphene to form large area van der Waals heterostructures. We reveal that the properties of the underlying substrate dictate properties of the layers and heterostructures, and that the direct synthesis of TMDs on epitaxial graphene exhibits atomically sharp interfaces. Our work has lead to a better understanding of vertical transport in 2D heterostructures, and we have identified new phenomenon in multi-junction heterostructures that has lead to resonance tunneling between layers and ultimately negative differential resistance.
