Abstract

Dependence of laser-induced desorption on both substrate temperature and emission angle have been studied in CdS by using the pulse mass counting method. The effective translational temperature of particles ejected toward the angle of 0 degree from the surface normal is much higher than that toward 45 degree . Arrhenius plots of desorption yields for the substrate temperature before laser irradiation show rather complicated features. Estimation of the temperature rise at surface by calculating the thermal diffusion equation gives the linear relationship in the Arrhenius plot. The enthalpy for desorption is estimated to be 0. 44 plus or minus 0. 1 eV. This value is considerably smaller than that (2. 2 eV) obtained in the free vacuum vaporization, suggesting the contribution of the electronic excitation effect.
