  • Current Activity :   My research work is to understand the correlated dynamics of spins and charges near the metal-insulator transitions of the materials having strong electron correlations. We study the electronic structure of transition metal-oxides, transition-metal doped dilute magnetic semiconductors, Oxide heterostructures and 2-dimensional layered materials. We also work in the field of photodetector and phototransistor applications using Gr.III-Nitride and 2-dimensional layered materials (van der Waals). Our current research goal is to develop Hall-bar structures for Quantum Hall Resistance standards (Metrology) by using Graphene prepared by thermal decomposition of SiC, where the resistance can be measured to an accuracy of about 1 part per billion.
