Research Highlights

Research Interests

Presently, I am maintaining research activities in the following areas through final year project students, postgraduate students, research staff and collaborative research interactions:

  • Fabrication of carbon nanotubes for high frequency applications (such as EM shielding, Slow wave devices, etc)
  • Application of 2D materials for photodetectors (using graphene / 2D thermoelectric materials, etc)
  • Preparation and characterization of wafer-scaled 2D materials and their heterostructures
  • Development of Filtered Cathodic Vacuum Arc technologies
  • Applications of diamond-like carbon / nanocomposites for wear resistive coatings
