Gallium selenide (GaSe)

Description:
Gallium selenide (GaSe) is a binary compound composed of gallium and selenium, notable for its semiconductor properties. It typically appears as a layered material, exhibiting a hexagonal crystal structure that allows for easy cleavage along its planes. GaSe is characterized by its direct bandgap, making it suitable for optoelectronic applications, including photodetectors and light-emitting devices. The compound is also known for its nonlinear optical properties, which enable its use in frequency conversion processes. GaSe is sensitive to moisture and air, necessitating careful handling and storage in inert atmospheres to prevent degradation. Additionally, it has a relatively high thermal stability, which contributes to its utility in various high-temperature applications. The material's electronic and optical characteristics can be tuned through doping and alloying, further expanding its potential applications in advanced electronic and photonic devices. Overall, gallium selenide is a significant material in the field of semiconductor technology and materials science.

    Gallium selenide

    Controlled Product
    CAS:
    <p>Gallium selenide is a semiconductor material that is used in the manufacture of photovoltaic cells. It can be produced by the chemical vapor deposition method, which consists of heating sodium carbonate and gallium in a vacuum chamber. The light emission from this material is then collected by an absorber layer, which converts it into electrical energy. Gallium selenide has been shown to have transport properties that are similar to those of copper, and is able to carry out oxidation-reduction reactions with 3-mercaptopropionic acid and molybdenum. This material has also been shown to be an effective thermal conductor, as it does not change its volume significantly under high temperatures. Gallium selenide can be synthesized chemically using diphenyl sulfoxide and selenide or electrochemically using boron nitride and copper electrodes.</p>
