Arsenic telluride (As2Te3)

Description:
Arsenic telluride (As2Te3) is a binary compound composed of arsenic and tellurium, notable for its semiconductor properties. It typically appears as a dark, crystalline solid and is characterized by its layered structure, which contributes to its unique electronic and optical properties. As2Te3 exhibits a high degree of anisotropy, meaning its physical properties can vary significantly depending on the direction of measurement. This compound is primarily used in the field of thermoelectrics and optoelectronics, particularly in applications involving infrared detectors and photovoltaic devices. Additionally, arsenic telluride has a relatively low melting point compared to other semiconductors, making it suitable for various fabrication processes. However, it is important to handle this substance with care due to the toxicity associated with arsenic, which poses health risks upon exposure. Overall, As2Te3 is a significant material in advanced technological applications, particularly in the development of next-generation electronic devices.
