I enjoy developing and understanding new materials that can improve existing technologies and create new ones. My current research is focused on semiconductor nanomaterials and thin films for optoelectronic applications like solar cells. I work on the synthesis and characterization of inorganic semiconductor and metallic thin films and nanoparticles. I use nanomaterials to make solar cells (photovoltaics) and other type of devices like thin film transistors (FETs) and photodetectors. Ultimately, I measure the efficiency and various optical and electronic properties of those devices and use the results as feedback to to innovate on and improve the conditions used during material growth and processing. Some material and thin film fabrication techniques I apply in my research are: -Physical Vapor Deposition (PVD) e.g. sputtering, thermal evaporation) -Thermal annealing processes i.e. rapid thermal annealing (RTP) -Colloidal synthesis of nanoparticles and quantum dots i.e. hot injection method -Sol-Gel i.e. for fabrication of oxide thin films In my work I use a number of material characterization techniques like -TEM, HREM, SAED, XRD, XPS, UPS, FT-IR, Raman, TGA, SEM, FIB, EDX, UV-Vis, PL, Cyclic Voltammetry Some of the most common optoelectronic measurements and analysis methods I utilize for understanding the physics of my semiconductor materials and devices are: -J-V characteristics under solar light -External quantum efficiency (EQE) measurements at short circuit and applied bias conditions -C-V characteristics and Mott-Schottky analysis -Transient photo- voltage and current (TPV, TPC) measurements -Stress and aging test of solar cells under various environmental conditions Some types of materials I am very familiar with are: -Quantum dots (e.g. PbS, CdS, PbSe) -Semiconductor Nanoparticles (e.g. Bi2S3, SnS) -Wide bandgap semiconductor films (e.g. ZnO, Ti2O) -Semiconductor polymers (e.g. P3HT, MEH-PPV).
