 Abstract: A nitride layer can be formed at low temperatures on GaAs(100) by simultaneous exposure to ammonia and UV photons in an ultrahigh vacuum environment. This process is a result of nonthermal photodissociation of adsorbed ammonia, initiated both by direct photon absorption and by attachment of hot substrate carriers. The nitride layer consists of a mixture of thermally stable GaN and volatile AsN; the latter desorbs below 800 K.
