Investigation on Metal Chalcogenide/Oxide Thin Films for Energy Device Applications

Engineered CdS thin films for PEC applications with experimental validation and DFT simulations.

Guided by: Dr. Raviprakash Y | Professor, Department of Physics, MIT Manipal

Engineered and optimised metal chalcogenide thin films CdS using thermal evaporation in a high-vacuum system to systematically control film thickness and doping concentration. Quantification of material suitability for Photoelectrochemical (PEC) applications through rigorous structural (XRD, SEM, UV-Vis) and electrochemical (EIS, Mott-Schottky) analysis. Validation of experimental results and prediction of charge carrier transport mechanisms by executing Density Functional Theory (DFT) simulations using the Quantum Espresso software package.
