Copper selenide (Cu2Se)

Description:

Copper selenide (Cu2Se) is a binary compound composed of copper and selenium, notable for its semiconductor properties and potential applications in thermoelectric devices and photovoltaics. It typically appears as a black or dark gray solid and has a layered crystal structure, which contributes to its unique electronic properties. Cu2Se exhibits a high electrical conductivity and a relatively low thermal conductivity, making it an attractive material for energy conversion applications. The compound is also known for its ability to undergo phase transitions, which can affect its thermoelectric performance. In terms of stability, Cu2Se is relatively stable under ambient conditions but can be sensitive to oxidation. Its synthesis can be achieved through various methods, including solid-state reactions and chemical vapor deposition. Additionally, copper selenide is of interest in materials science and nanotechnology due to its potential for use in nanostructured materials and devices. Safety precautions should be observed when handling this compound, as both copper and selenium can pose health risks in certain forms.

Copper(I) selenide (CuSe) is a material that has been studied for its potential use in photocatalytic applications. It can be used to convert water into hydrogen and oxygen gas by using sunlight as the energy source. The adsorption of CuSe occurs through a mechanism that is not well understood, but it is believed to involve the formation of a solid solution between CuSe and the substrate. The synergistic effects of CuSe with other materials have also been studied, such as TiO2, ZnO, ZrO2, and CeO2. The optical properties of CuSe depend on the crystalline structure and lattice constant. Copper(I) selenide has been shown to be photocatalytic for molecules with either C-H or N-H bonds. Morphology studies show that CuSe has a hexagonal crystal structure with space group Fd-3m. Transport properties such as diffusion coefficients and surface-enhanced Ram
