arsenidealuminum
Arsenide aluminum, also known as aluminum arsenide (AlAs), is a compound with the chemical formula AlAs. It is a semiconductor material belonging to the III-V group of elements, meaning it is composed of elements from Group III (aluminum) and Group V (arsenic) of the periodic table. AlAs is known for its relatively wide band gap, which makes it useful in certain electronic and optoelectronic applications. It crystallizes in the zincblende structure, which is common for many III-V semiconductors.
The properties of aluminum arsenide are distinct from its constituent elements. It is a hard, brittle solid.
