•Carried out theoretical and xperimental (Raman spectroscopy) studies of the vibrational properties of core-shell semiconductor nanowires for exploring their potential in optoelectronics and micro-electronics. •Strain characterization of the SiGe nanowire heterostructures using micro / macro Raman spectroscopy. •Developed elastic continuum models of the strain and compared it with realistic computer simulations created by ABAQUS to analyze the strain effects in novel III-V and Group-IV core-shell nanowire.

• Taught undergraduate physics courses such as Introduction to Physics, Mechanics, Electricity and Magnetism and Modern Physics. • Interacted with students and helped them with their assignments.

• Successfully studied the vibrational properties of precursor molecules used for the development of new CVD methods for semiconductor growth. • Used micro-Raman and FTIR spectroscopy to confirm the phonon modes of the precursor molecules. • Carried out photo-luminescence to investigate the energy bandgaps in n-type and p-type doped materials. • Carried out photoluminescence and Raman studies for exploring the potential of novel Group III-V and Group-IV materials in o
