Copper selenide nanomaterials are recognized to possess thermoelectric characteristics, becoming a strong contender unite materials science and energy technology with effective use in practical applications extreme environments.
Cu2ZnSnS4 (CZTS) nanoparticles (NPs) are synthesized by sonochemical technique. The composition analysis showed the NPs to be stoichiometric. X-ray diffraction confirms CZTS phase and tetragonal unit cell structure. Three peaks corresponding have been observed in Raman spectroscopy positioned at 293.47 cm−1, 373.8 336.67 cm−1. electron selected area faded rings with spot patterns indicating crystalline nature. a direct optical bandgap of 1.62 eV, being ascertained absorbance spectroscopy....
Owning a narrow bandgap, remarkable optical and electrical properties with notable stability has made cadmium telluride (CdTe) an immensely vital semiconductor to develop cutting-edge optoelectronics. Taking these in account, CdTe thin film is deposited employing the chemical bath deposition (CBD) technique. The X-ray diffraction analysis of as-deposited unveiled composite crystalline structure, incorporating cubic, hexagonal, tetragonal phases. energy dispersive photoelectron spectroscopy...
Looking at the literature survey, this seems to be first report on growth of a copper antimony diselenide (CuSbSe 2 ) single crystal with 5.8 cm length and 1.0 diameter by vertical Bridgman technique.
Nanoparticles of tin telluride (SnTe) are prepared by the hydrothermal method. The analysis composition showed nanoparticles to be stoichiometric. structure and phase determined X-ray diffraction. It possess cubic SnTe phase. spherical shape is validated electron microscopy. Raman spectrum revealed characteristic peak associated with SnTe. thermal study done comprehend nature. in inert nitrogen for heating rates 5, 10, 15 20 K•min−1 range temperature between ambient 1053 K. decompose three...
This study marks the first report on growth of Cu x Sb 1− Se 2 ( = 0.2, 0.4, 0.6, 0.8) crystals using Bridgman technique. Results shows that these can be considered as a choice for thermoelectric well photodetection applications.
