· JVASP-155364· CdCu2TeS4

CdCu2TeS4 is a quaternary compound semiconductor belonging to the chalcogenide family, combining cadmium, copper, tellurium, and sulfur elements. This material is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its tunable bandgap and mixed-metal composition offer potential advantages in light absorption and charge carrier transport compared to binary or ternary semiconductors. Engineers and researchers consider this compound family for next-generation solar cells, photodetectors, and thermoelectric devices where the combination of earth-abundant copper with cadmium enables cost-effective alternatives to conventional III-V semiconductors.
