Exploring optoelectronic structure and thermoelectricity of recent photoconductive chalcogenides compounds CsCdInQ3 (Q = Se, Te)
Original language description
The photoconductive quaternaries, CsCdInQ3 (Q = Se, Te), have been synthesized recently and have shown to be potential materials for hard X-ray and ?-ray detection. These materials have relatively high densities and band gap in range of 1.5MINUS SIGN 3 eV, which make them fulfilling the requirement of hard detection devices. In the present work, we investigate the metal chalcogenide CsCdInQ3 as deduced from a full potential linearize augmented plane wave method based on density functional formalism. Thedirect band gap is estimated at level of EVGGA functional, as 2.11 and 1.75 eV for CsCdInSe3 and CsCdInTe3 respectively. These values are in good agreement with the experimental measurements (2.40 and 1.78 eV) performed from solid-state UVMINUS SIGN visoptical spectroscopy. Optical parameters including the dielectric constant, absorption coefficient, energy loss function reflectivity and refractive index are also reported to investigate the potential role of these metal chalcogenide co
