I am Sanjay Kr. Jana from Indian Institute of Technology Kharagpur, India. Presently I am pursuing my PhD at Advanced Technology Development Center in IIT Kharagpur. My research interest is MBE growth, in-situ and ex-situ characterization, and wafer level device fabrication of III-N/As based materials on sapphire and Si substrates for electronics (e.g. HEMT) and optoelectronics (e.g. LED) applications. I have authored and co-authored sixpeer reviewedjournal papers and more than ten international conference papers during PhD period on the field of III-nitride and Arsenidebased thin films and QDs heterostructures grown by MBE.
