CdBiSe₂I is a layered ternary ceramic compound belonging to the chalcogenide family, combining cadmium, bismuth, selenium, and iodine elements. This is a research-phase material primarily investigated for optoelectronic and photovoltaic applications, where the layered crystal structure and tunable bandgap make it a candidate for solar cells, photodetectors, and infrared sensing devices. The material's weak interlayer bonding and potential for mechanical exfoliation align it with two-dimensional materials research, offering engineers an alternative platform for exploring next-generation semiconductor heterostructures and flexible electronic devices.
