Abstract
The primary ions strike the target in randomly distributed points of its surface, potentially leading to the creation of surface roughness. The first involves exploring the variation in density near surface target which is challenging to measure. The second focuses on observing alterations in the surface topography of the target by measuring the amount of deformation in the geometric structure. This brief work is clearly needed to clarify the first approach by adopting the feasible expressions to establish the dependence of the range straggling, energy and dose of ions beam on the basic mechanisms leading to surface roughness by introducing new parameter described the unchanged surface density rate. This parameter predicts the frequency of presence roughness phenomena. The results of our simulations performed for an amorphous target are in perfect agreement with experimental results obtained by Wach et al.
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.
