Metalloid nanocrystals may enable lithium-ion batteries to be replaced by more powerful sodium ion batteries. Tellurium, which is a semiconductor in its standard state, is used mainly as a component in type II/VI semiconducting-chalcogenides; these have applications in electro-optics and electronics. Cadmium telluride (CdTe) is used in solar modules for its high conversion efficiency, low manufacturing costs, and large band gap of 1.44 eV, letting it absorb a wide range of wavelengths. Bismuth telluride (BiTe), alloyed with selenium and antimony, is a component of thermoelectric devices used for refrigeration or portable power generation. Five metalloids—boron, silicon, germanium, arsenic, and antimony—can be
GeSbTe antimony and tellurium, such as tris-dimethylamino antimony (TDMASb) and di-isopropyl telluride (DIPTe) respectively, to grow GeSbTe and other chalcogenide films of very high purity by metalorganic chemical vapor deposition (MOCVD). Dimethylamino germanium trichloride (DMAGeC) is also reported as the chloride containing and a superior dimethylaminogermanium precursor for Ge deposition by MOCVD. GeSbTe is a ternary compound of germanium, antimony, and tellurium, with composition GeTe-SbTe. In the GeSbTe system, there is a pseudo-line as shown upon which most of the alloys lie. Moving down this pseudo-line, it can be seen that as we go from SbTe to GeTe, the melting point
