Abstract

The visible-laser sublimation of CdTe, HgCdTe, CdS, and GaAs has been studied. A dynamic light guiding has been identified with an active feedback mechanism and is connected to the observation of 0.4 μm wide single-mode guiding structures during deep etching. The incipient stages of sublimation have been studied by mass spectrometry and are discussed in relation to diffusion mechanisms in the solid state.
