Aluminum antimonide is an intermetallic compound of aluminum and antimony and a III-V compound semiconductor. Aluminum antimonide is of interest as a potential material for solar cells., It may also be added to other III-V compound semiconductors. With these ternary semiconductors ( for example, AlInSb, AlGaSb and AlAsSb. ), It is possible to better adjust the band gap of the solar spectrum.
