PhD Thesis title:

"Studies on Gallium Iron Antimonide, a Novel III-V Diluted Magnetic Semiconductor"

Research interests :

1. Surface and interface characterization of metal/semiconductor and related device materials in bulk and in in nano-scale structures using Secondary Ion Mass Spectrometry.

2. Crystal growth of interesting compound semiconductor materials (bulk and nanogranular).

3. Synthesis (using different chemical and vapour evaporation methods) & characterization of technologically important materials and related devices using multi-disciplinary analytical techniques like XPS, SIMS, XRD, Raman, SEM, PL, EL,  TEM etc.

4. Study of defects using luminescence techniques.

5. Ion-solid interaction and modifications of surfaces and interfaces using low energy (keV) and high energy (MeV) ions.

6. Magnetic nanostructures and their properties

Experience :

(a) JRF (Aug'95 to July'96) in Raman Research Institute-Bangalore
