Paper Abstract

The scattering of N2 from Si(100) was studied using state-selective detection and molecular beam techniques. Both trapping-desorption and direct inelastic scattering channels were observed. For an incident N2 energy of 0.08 eV, the trapping-desorption probability was found to be essentially unity for surface temperatures between 93 K and 573 K. The velocity and rotational state distributions of the desorbing molecules show that the nitrogen is fully accommodate with the surface. For an incident energy of 0.29 eV, a direct inelastic channel as well as the trapping-desorption channel was present. The rotational state distributions of both channels were studied as a function of surface temperature and incident energy.
