Abstract : CdS single crystals are heated linearly in time while the desorption of gas is monitored continuously on a mass spectrometric located directly in front of the crystal. A desorption curve of CdS for amu 16 is given for a temperature range of -180C to +225C. Four sites (or layers) are seen to desorb with certain activation energies. Changes in surface structure are suggested since the process is not reproducible. (Author)
