MS thesis on "Investigation of Electrical and Magneto Transport Properties of Reduced Graphene Oxide Thin Films"Project-1: A Study of structural, electrical and optical properties of wafer-scale reduced graphene oxide (RGO) thin film. (3 peer-reviewed journals) Developed the fabrication of wafer scale RGO thin films by pulsed lased deposition technique and characterized the film by XRD, Raman spectroscopy, Photoluminescence and SEM. Correlated the charge carrier mobility with different level of reduction on RGO thin films and determined the optimal process parameters in order to get higher charge carrier mobility.  Improved the growth process by tuning the growth parameters to obtain extremely large positive (160%) and negative magnetoresistance.Project- 2: Fabrication and characterization of standalone Copper oxide nanoparticles and ZnO-CuO nanocomposite for improved photovoltaics & photocatalytic applications (3 peer-reviewed journals) Hydrothermally synthesized standalone Copper oxide nanoparticles and ZnO-CuO nanocomposite and characterized the nanostructures by XRD, Raman spectroscopy, Photoluminescence and SEM. Optically active nanostructured phase mixture of copper oxides were used to fabricate nanopowder-thin film (CuO-ZnO) solarcell devices to obtain η ~2.9%, which exceeded all the reported values for ZnO/CuO based solar cells. Investigated the growth mechanism and optimum composition of ZnO and CuO to achieve better photocatalytic activity under UV-vis spectroscopy.Courses: MAT 770 - Vapor Synthesis of Materials; MAT 760 – Experiments/Physical Characterization ; PHY 675 - Quantum Mechanics; MAT 720 - Advanced Quantum Mechanics; MAT 681 - Structure of Solids , MAT 640 - Thermodynamics of Materials; MAT 790 - Statistical Applctns/Matrls Sc; MAT 651 - Intro to Materials science.
