Paper Abstract

We study the periodic damage structures that can be produced don the rough-surface of semiconductor when they are irradiated with a single beam of intense laser radiation. We observed a formation of periodic surface structures for porous Si with microscopic surface roughens. In the case of more strong rough Ge we observed an opposite effect to ripple formation: i.e. an effective destruction of resonance Fourier components of the random disturbed surface.
