Research Interests
Growth of thin-film and hetero-structure: Growth of ferro-magnetic/ferro-electric/multiferroic metal oxide thin-films and hetero-structures. Growth & study of opto-electronic properties of Graphene/Graphene Oxide (GO) & reduced Graphene Oxide (rGO) thin-films using CVD & PLD. Growth of 2D-TMDC & 2D-TMDC/Metal Oxide hetero-structures using CVD & PLD.
Wettability studies of metal-oxide thin-films: Systematic study of water contact angle (WCA) of of PLD grown epitaxial R2O3 (R = Lu, Sm, Tm, Tb etc.) thin-films and the temporal evolution of the WCA. Study of correlation of nano-scale WCA to micro WCA using novel f-d curve Study Of biological interaction of PLD grown epitaxial R2O3 thin-films with human osteoblast and fibroblast cells. Study on the effect of Oxygen vacancy on the WCA of transition metal based [i.e. – SrTiO3, LaAlO3) and rare-earth based [i.e. - R2O3 (R = Lu, Sm, Tm, Tb etc.)] oxides.
Study of magnetism in novel nano-structures: Novel soft-ferromagnetism in transition metal based metal-organic systems like Me(X)n. [(Me = Ru, Co, Fe, Pt, Pd etc.); (X=PAP; PCP etc.); (n=2,3,4 etc.)]. Study of Quantum Correction in Disordered antiferromagnet (Cr & Mn). Ferromagnetic behavior in magnetic Quantum Dot (MQD) like FeCeTeS. Role of interface in ferromagnetic, magneto-trasport and ferroelectric properties of perovskite and double perovskite (DP) super lattice structure.
Optical studies of Rare-earth based perovskites: Growth & Study of Ce doped NdGaO3 thin-films to realize the concept of super-hydrogenic dopant. Study of sharp Photoluminescence lines of various common oxide substrates including (but not limited to) LaAlO3, SrTiO3, DyScO3, NdGaO3, NdAlO3
