My work goal is to develop UV-Visible photodetectors (PDs) from Porous silicon (PS) based hybrid Metal-Semiconductor-Metal (MSM) hetero-structures. Different metal sulfides and metal oxides are deposited or incorporated on PS surface to achieve those hybrid structure. Basic goal is to attain High responsive and high speed PDs
