On the Mechanism of High-Yield Desorptionsorption step. Thus, this step could variously be thermal or electronic but the collisions lead to a primary distribution function having the form appropriate to a “Knudsen layer”. We show how there are four phases due to the collisions: that of the Knudsen layer (the primary phase), that of unstead

Reinhold Sellien,Helmut Sellienwn that in the presence of coadsorbed impurities both the widths and the shift of atomic levels with position can be strongly modified compared to the clean metal case. Such changes can significantly alter the probability for charge transfer between an atom and a surface. This effect is illustrated

Reinhold Sellien,Helmut Selliennce of final-state effects on the trajectories of desorbed ions. It is believed that the initial repulsive forces propelling ESD ions from surfaces often originate from 2 hole repulsive states which act along the original chemical bond direction[l]. However, final state effects, including image fiel

Reinhold Sellien,Helmut Sellienactions. The photochemical processes which can occur are photodesorption, photodissociation, and photoreaction of the adsorbed molecules. These photo-induced processes have been observed for a range of diatomic and polyatomic molecules on metal, semimetal, semiconductor, and insulator surfaces. Surf
