Paper Abstract

The time-of-flight method was used to study the laser- stimulated desorption of atoms and molecules from the surface of ZnO. The kinetic energy distributions of desorbed oxygen molecules are characterized by the presence of two forms: 'fast' with kinetic temperature approximately equals 3000 K and 'slow' with Tk approximately equals 550 K. The first one is typical for desorption excitation in the self- absorption region (h(nu) > Eg), and the second one in the transparent region. Two non-thermal mechanisms of desorption are suggested.
