What Is The Conductivity Of Aluminium Selenide?

Aluminum selenide (Al2Se3) is a semiconductor material with moderate electrical conductivity. Its electrical conductivity depends on factors such as temperature, impurities, and crystalline structure.

At room temperature, pure aluminum selenide has a low electrical conductivity of around 10^-7 to 10^-9 Siemens per meter (S/m), which is similar to some insulating materials. However, when doped with certain impurities, such as copper or silver, its conductivity can increase by several orders of magnitude.

The electrical conductivity of aluminum selenide also increases with temperature due to an increase in the number of free charge carriers. This behavior is typical of most semiconducting materials.

In terms of crystal structures, aluminum selenide can exist in both amorphous and crystalline forms. The crystalline form tends to have better electrical conductivity than the amorphous form.

Overall, the conductivity of aluminum selenide is moderate compared to metals like copper and silver but higher than many insulating materials. Its properties make it suitable for use in electronic devices such as photovoltaic cells and sensors.
