Copper Iodide Powder

 CuI Powder; have generated great interest for their promising applications in high power, high frequency electronic and optoelectronic devices. These compounds exhibit many unusual properties, such as a large bandgap, negative spin-orbit splitting, a large temperature dependence of resistivity and analogous diamagnetic behavior. Copper Iodide Powder is a semiconductor compound I–VII that crystallizes in three different phases at atmospheric pressure; these are phases a, b and c. The low-temperature c-phase is a broadband-range semiconductor whose energy range is close to eV and the exciton binding energy is fairly high equal to 62 meV, making it a potential candidate for optoelectronic applications. The c-phase is also known as a potentially ultrafast scintillation material with a short decay time of 90 picoseconds at room temperature. Copper Iodide Powder is also known as a superionic conductor with a zinc mixture structure. The ionic, thermal and electronic conductivity of these compounds has been studied in detail by several authors. From a chemical point of view. Recent studies indicate that p-CuI was used as the complete conductor (solid electrolyte) in place of liquid electrolytes in dye-sensitized solid-state solar cells. It is due to the liquid electrolyte in the DSSSC that leads to various technological problems such as decomposition of the dye during photochemical reaction, evaporation of solvents, degradation and imperfection of the seal. Numerous attempts have been made by many authors to grow a highly pure p-type CuI single crystal by cyclic evaporation and hydrothermal methods.
