materials physics and condensed matter (experimental)
My research is focused on rational design, controlled synthesis, and coherent measurement of novel nanostructured materials. The material systems that I am currently interested in include spin-orbit coupled oxides, topological insulators and metals. I use pulsed laser deposition to fabricate thin films and planar heterostructures, and chemical vapor deposition to grow 1D nanowires and 2D nanoplatelets. I am particularly interested in exploring their emergent physical (structural, electrical, magnetic and thermoelectric) properties that arise from unique aspects associated with the nanoscale geometry, and aim to understand the underlying physical origins via correlated nano-scale measurements using multi-functional scanning probe microscopy and low temperature magnetization and transport techniques.
