RESEARCH

My research is based on Focused Ion Beam (FIB) process for nanofabrication and its application in creating novel nanostructures. I am interested in ion solid interactions for semiconductors and novel materials such as graphene towards  material removal (milling or etching), in order to create 2D/3D structures at both micro- and nano-scale for diverse applications in optics and materials science, such as anti-reflection, color filters, and sensors, to name a few.

I have experience with FIB based nano-fabrication, sample preparation and have been a regular user of microscopic characterization techniques such as Raman Spectroscopy, Atomic Force Microscopy (AFM), with theoretical & modeling exposure to Electromagnetic Finite-Difference Time-Domain (FDTD) Calculations- Lumerical, Molecular Dynamics (MD) Calculations- LAMMPS, Finite Element Modeling- ANSYS.

I also worked on ion induced, in-situ controlled manipulation of nanostructures and investigation through molecular dynamics (MD) simulations, in order to arrive at a feasible methodology. This work is critical for 3D nanofabrication with promising nanoscale-controlled manipulation, strain engineering of nanostructures, opening new avenues in the diverse field of ion beams and applications beyond material science for realization of future nanoscale devices.
