RESEARCH SKILLS

v    Device fabrication: I have experience in fabrication of organic solar cell, , perovskite solar cells, organic light emitting diode. For the fabrication of these devices I was used photolithography, clean room, glove box, sputtering, thermal evaporation, spin coating, etc. Besides these, I also possess experience in the fabrication of Magneto-tunnel junction and organic based spin valve.

v     Electrical Transport Measurement: I have studied electrical transport in above devices as well as nanostructured thin film by using a range of techniques, cryogenic system, I-V, C-V, Hall effect, Magnetoresistance,  impedance spectroscopy, solar simulator, etc.

v     Photoinduced Charge/Spin Injection & Transport Mechanism: I had studied the mechanism of exciton dissociation at Organic/inorganic interface by using spectroscopic techniques such as: Photoluminescence, time-resolved fluorescence spectroscopy (TRFS). Similarly for spin injection and transport in FM/Organic hetrojunction is carried out by two photon photoemission spectroscopy. I am highly interested to work in this area.

v     Characterization: For the characterization of material and devices I have been extensively used spectroscopic techniques (UV-Vis abs, PL, TRFS, Raman, FTIR, etc.), Electrochemical analyzer, TGA, DSC, AFM, XRD, Electrical characterization systems (I, V, T, R, σ, Solar cells efficiency), Magnetic measurement (PPMS, Magneto-resistance at different temperature).

v     Synthesis: I have quite experience in the synthesis of polymers (P3HT, PANI), QDs (CdS, CdTe, CdSe) and polymer/QDs nanocomposites, in-situ as well ex-situ. Besides these I also synthesized the functionalized-graphene and funct-graphene/QDs Nanocomposites.

v     Computer Skills: Extensive computer skills including MS. Office, Matlab, MathCAD (for the fitting of electrical transport), Genx, (for X-ray and Neutron reflectivity simulation), Z-view (for equivalent circuit for solar cells), Origin etc. I also have experience on python for simulating X-ray reflectivity of multilayers.
