Abstract

This paper presents a review of recent experimental and theoretical work on surface modification of alkali halides due to electronic excitations caused by electron and photon irradiation. In particular, several examples of free exciton and hot electron-hole pair formation in ionic materials are given. It is demonstrated that evolution of these primary excitations with subsequent defect formation and diffusion from the bulk to the surface, leads to dynamic surface modification and sputtering, often periodically varying with the irradiation dose. In turn, modification of the surface topography could affect and modulate periodically, the diffusion processes driving thedefects from the bulk of the material towards its surface. Spectacular examples of such oscillatory yield dependencies, and corresponding surface nanostructure formation and evolution, are shown for electron- and photon-irradiated NaCl, KBr and KCI(0 0 1) surfaces of bulk crystals and thin epitaxial films. Important applications of these findings for quantitative characterisation of insulator surfaces and mass spectrometry are presented. (C) 2001 Elsevier Science Ltd. All rights reserved.
