Biography and Research Information
OverviewAI-generated summary
Koushik Biswas's research investigates the properties of inorganic materials, with a particular focus on their applications in optoelectronics and solar energy conversion. His work has explored the electronic structures and luminescence in halide perovskites, such as Cs4PbBr6/CsPbBr3, and the potential of bismuth and antimony-based oxyhalides and chalcohalides for optoelectronic devices. Biswas has also examined the role of multivalent elements, like tin in Cu2ZnSnS4, in inorganic solar absorbers, contributing to the understanding of carrier self-trapping and luminescence in scintillator materials like Cesium Hafnium Chloride. His research extends to the design and synthesis of transparent oxides for hole conduction, with studies on materials like Cu3VO4 and Ag3VO4. His publications include work on metal halide semiconductors beyond lead-based perovskites for optoelectronic applications.
