Translational Heating of D2 Molecules Thermally Desorbed from Si(100) and Ge(100) Surfaces
The translational energies of D2 molecules thermally desorbed from the Si(100) and Ge(100) surfacesunder a heating rate of 6 K=s have been measured. In contrast to the previous laser desorption study,results show a considerable translational heating; the observed translational temperature is about 3 timeshigher than the desorption temperature for both surfaces. This fact indicates that energy barriers foradsorption are present even in the desorption pathway. Detailed balance is applicable to the adsorption anddesorption dynamics of hydrogen on the Si(100) surface
