Gallium Telluride Powder

Gallium telluride powder was grown from high purity elemental precursor materials with tin (Sn) and germanium (Ge). An overview of the Bridgman growth technique is provided along with the description and temperature profile of the installed growth oven. The growth process of the GaTe powder and its subsequent processing are discussed. Characterization includes identification of GaTe compounds, stoichiometry and defect analysis, optical and electrical characteristics. Then it ends with the manufacture of the radiation detector and subsequent characterization techniques. It has been shown that the properties of GaTe surfaces strongly influence the properties of the material and are strongly influenced by chemical modifications by S2 ions. The results of the study of the surface composition using techniques such as X-ray photoelectron spectroscopy (XPS) and energy-dispersive scanning electron microscopy X-ray detection (SEM-EDAX). When combined, gallium and tellurium create an IIIB-VIA semiconductor that is a member of the gallium chalcogenide family that includes GaTe, GaSe, and GaS. This relatively underdeveloped semiconductor has a high atomic number and broadband energy, which is important for the use of GaTe as a window material for solar cells and radiation detectors. The physical and chemical properties of this material are subject to conventional material handling procedures and moderate temperature crystal growth. For these reasons, Gallium telluride powder has recently gained special appeal due to its potential use in the fields of optoelectronic devices, terahertz sources, radiation detectors, and solar cells. Due to these different crystallographic orientations along the intra- and interlayer directions, the Gallium telluride powder shows great anisotropy in its optical and electrical properties.
