Control of initial growth processes of epitaxial films using pulsed molecular beams - art. no. 153404

Kinetics of epitaxial thin film growth was analyzed from the experiments us ing pulsed organic molecular beams. It was found that a minimum appears in the nucleation density as a function of on-off cycle time when the substrat e temperature is near the threshold between growth and reevaporation. This feature can be explained by assuming desorption of molecules induced by mut ual collision on the surface, for which orientation-sensitive intermolecula r forces are responsible.
