Abstract

It has recently been shown that single crystal CdS, illuminated by light whose photon energy exceeds the bandgap, can eject particles from its surface while the temperature is well below the value required for vacuum sublimation. This phenomenon has obvious applications to the fabrication of surface structures as well as to the production of thin films that can show good CdS stoichiometry. This work will present several data on the morphology of the etched surface and its dependance on crystal orientation; results of an analysis of the recondensed thin film phase from the ejected material will also be shown. Emphasis will be devoted to examples of high resolution surface structures fabricated with this technique.
