Abstract

A model is presented which describes the time and spatial frequency evolution of periodic structures formed during metal atom deposition arising from UV laser-induced photodissociation of organometallics. In addition to the occurrence of rapid growth of spatial frequencies which allow direct coupling of the incident radiation to the surface-plasmon polariton (SPP), a high-wavevector profile component, associated with the interference of counterpropagating SPP waves, also develops with extremely high gain but without feedback. Pump/probe diffraction methods foo verifying the predictions and elucidating the surface modification of photodissociation are briefly proposed. Deposition of aluminum by photolysis of (CH₃)₃Al at 257 nm is chosen as the model system.
