TlCuSe2

TlCuSe₂ is a ternary chalcogenide semiconductor compound composed of thallium, copper, and selenium, belonging to the family of I-III-VI₂ semiconductors. This material is primarily of research interest for optoelectronic and thermoelectric applications, where its tunable bandgap and moderate mechanical stiffness make it a candidate for photovoltaic devices, infrared detectors, and solid-state thermoelectric generators. While not yet commercially widespread, TlCuSe₂ represents an emerging class of earth-abundant alternatives to conventional III-V semiconductors, offering potential advantages in cost and processing flexibility for specialized sensing and energy conversion applications.
