Research Interests

His research focuses on synthesis of next generation low-dimensional materials and understanding their optical, electrical, mechanical, and magnetic properties using state-of-art experimental and theoretical techniques. Research aims at incorporating these unusual materials in unique applications that are otherwise unattainable using conventional materials.

  • Two-dimensional materials: Transition Metal Dichalcogenides, Graphene & derivatives
  • Next-generation materials: Growth & synthesis
  • Flexible electronics: Solar cells, sensors / detectors, diodes, and Field-effect transistors (FETs)
  • Optical Spectroscopy: Photoluminescence, Raman, Photo-current, scanning photocurrent, micro-absorption / reflection
  • Computational Materials Design: Density Functional Theory (DFT) and molecular dynamics (MD).

Graduate Faculties

  • Materials Science & Engineering
