Indium Arsenide Nanoparticles

Indium arsenide is similar to gallium arsenide and is a direct bandgap material. Indium arsenide is sometimes used together with indium phosphide. Alloyed with gallium arsenide it forms indium gallium arsenide - a material with band gap dependent on In/Ga ratio, a method principally similar to alloying indium nitride with gallium nitride to yield indium gallium nitride.
