Abstract
The problem of radiation-physical processes in topological insulators is discussed. As an example, а “Coulomb explosion” on the surface of topological insulators initiated by the K-ionization of a negative ion and the subsequent Auger cascade, which carries a large Auger charge Z\( \gg \) 1 to the valence states of the local region, is considered. It is shown that when electrons are replaced by Majorana fermions, the neutralization time increases; that is, in topological insulators the “Coulomb explosion” is more likely than that in a conventional insulator. A conclusion is drawn about a significant modification of the processes of subthreshold radiation physics of condensed matter in the case of topological insulators.
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
