Biography

Dr. Rakesh Kumar is an Associate Professor in the Department of Physics. In 2006, he received his Ph.D. degree from Indian Institute of Technology Bombay, where he worked on superconductivity and magnetism. Thereafter he joined Tata Institute of Fundamental Research, Mumbai as a Visiting Fellow, where he continued his research work on magnetic materials. In 2007, he moved to University of Peirre and Marie Curie, Paris, France to work on graphene and other two dimensional layered materials like InSe, NbSe2, BSCCO superconductors and Bismuth. He worked on fabrication as well as electrical characterization of Field Effect Transistors (FETs). His current research interests are in fabrication of nanodevices from graphene and other low dimensional materials and the involved nanophysics, specially their strongly correlated electrons behaviors in the low dimensional systems.

Research

Our T-GraMS laboratory is working on experimental and theoretical condensed Matter Physics. We are working on two dimensional and three-dimensional materials for investigating its interesting Physics towards its applications. Research works are being carried out on topological materials, perovskite materials, two-dimensional materials, magnetic materials and superconducting materials. In brief, our research works are focused for investigating (a) how the topological phase transition can affect the XMR effects (b) Effect of interlayers couplings on the electronic properties in magnetic and superconducting two-dimensional materials (c) Tuning the electronic properties of 2D materials (d) Application of two-dimensional materials in flexible electronics and Gas-sensing and (e) study of superconductivity and magnetism in HTSC and layered 2D materials.
