Dmitry (Dima) Ruzmetov is a Guest Researcher in the Functional Nanostructured Materials Group (MML). He works full-time as a physicist at the US Army Research Lab. He received a Diploma in Physics from Lomonosov Moscow State University, Russia, and an M.S. and Ph.D. in Physics from Indiana University. His doctoral research focused on magneto-transport properties of diluted magnetic semiconductors. Dmitry is currently investigating the potential of 2D semiconductors to improve the speed and power performance of present microelectronic devices. He studies heterojunctions of epitaxial transition metal dichalcogenides and conventional (3D) semiconductors, such as MoS2/GaN system. Dmitry is collaborating with Dr. Albert Davydov on the structural and electrical characterization of epitaxial 2D/3D semiconductor heterojunctions.
