Creating and Exploring Atomically-Thin Materials and Heterostructures

The last decade has seen an exponential growth in the science and technology of two-dimensional materials.  Beyond graphene, there is a huge variety of layered materials that range in properties from insulating to superconducting. Furthermore, heterogeneous stacking of 2D materials also allows for additional “dimensionality” for band structure engineering. In this talk, I will discuss recent breakthroughs in two-dimensional atomic layer synthesis and properties, including novel 2D heterostructures and realization of unique 2D allotropes of 3D materials (e.g. 2D-GaN and Ga2O3). Our recent works demonstrate that the properties and doping of 2D materials, especially synthetic 2D materials, are extremely sensitive to the substrate choice. I will discuss substrate impact on 2D layer growth and properties, doping of 2D materials, selective area synthesis of 2D materials, and 2D nitrides beyond hBN. Our work and the work of our collaborators has lead to a better understanding of how substrate not only impacts 2D crystal quality, but also doping efficiency in 2D materials, and stabalization of nitrides at their quantum limit.

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. In 2012, he 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. In July 2015, he became Co-Director of the NSF I/UCRC Center for Atomically Thin Multifunctional Coatings (ATOMIC), and most recently, in 2016, he became the Director of User Programs for the NSF-funded 2D Crystal Consortium. He has authored or co-authored over 150 peer reviewed journal publications with a significant focus on low dimensional electronic materials. He has patents on chemical and neutron detection, and various pending patents related to 2D materials.
