MSc. Shreelekha Mishra
Shreelekha Mishra’s research focuses on the growth, characterization, and modeling of transparent conducting oxide (TCO) thin films under ambient and variable temperature conditions. She investigates band dispersion, optical shifts, and phonon-scattering effects on charge transport, emphasizing temperature-dependent carrier dynamics, effective mass variation, and defect-driven electronic structure changes. Using spectroscopic and electrical techniques, her modeling incorporates nonparabolic bands and scattering mechanisms to predict and optimize conductivity and transparency in TCO-based devices.

Samik Yanque Amable
I am a physics graduate and early-career researcher in the Materials Science and Renewable Energies (MatER) group at PUCP–Peru. My current work focuses on developing and understanding high-mobility zinc-doped indium oxide (ZIO) thin films grown by low-power RF sputtering for use as transparent conducting electrodes in perovskite/silicon tandem solar cells. I am particularly interested in how soft-sputtering processes at room temperature can enable stable, high-movility TCOs compatible with sensitive photovoltaic cells.
