• Computed the lattice dynamics in face-centred cubic (FCC) systems, using an empirical pair potential model to reduce computational time.• Developed a modified scheme to analyze the effect of surface vibrations on the density of states of gold nanoparticles up to 20,000 atoms.

• Explored the properties of thermoelectric heat capturing materials and its application in electronic devices.• Performed pulsed laser deposition and photolithography in the clean room to develop perovskite thin films.• Evaluated the capacitance behaviour near the Curie Temperature in perovskite materials using a cryogenic probe station
