プロフィール概要

I had completed my Ph.D in computational material science from IIT Hyderabad in May 2014. I was awarded the Young scientist award in physics from Dr. K.V Rao scientific society in 2013, Telangana. India and awarded for outstanding academic performance at IIT-Hyderabad, Hyderabad, Telangana. India in 2011. I had worked with Prof. U V Waghmare in JNCASR, Bangalore, India, as a research associate from March-2016 to Oct-2018. Prior to this, I worked as an Assistant Professor from July-2014 to Feb-2016 in Dayananda Sagar college of engineering, Bangalore, India. I have been involved in doing ab-initio study in different types of materials like magnetic materials, intermetallic, superconducting materials, interface study in semiconductor materials, etc. Currently, my research interest is focused on catalysis.

Fermi surface topology changes are found for all the isostructural AB3 compounds under compression (at V/V0 = 0.90 for LaPb3 (pressure = 8 GPa), at V/V0 = 0.98 for AIn3 (pressure = 1.5 GPa), at V/V0 = 0.80 for ATl3 (pressure in excess of 18 GPa)) apart from YPb3, although its electronic structure at zero pressure is very similar to that of LaPb3. For LaPb3 a softening of the C44 elastic constant under pressure (equivalent to 8 GPa) may be related to the appearance of a new hole pocket around the X point. From the calculated elastic properties and other mechanical properties, all the compounds investigated are found to be ductile in nature with elastic anisotropy. The states at the Fermi level (EF) are dominated by B p states with significant contributions from the A d states. For the La compounds, small hybridizations of the La f states also occur around EF.}} .
