چکیده

The results of a research on the surface morphology nanostructured nickel after high-fluence irradiation with 30 keV argon ions have been presented. nanostructure in was formed by high-pressure torsion deformation. It has shown that deformation nanostructuring and subsequent ion-beam sputtering allows receiving uniformly coated submicron cones. thermal stability obtained cone-shaped structure determined. Keywords: nanostructure, torsion, ion irradiation, cones, stability.

Morphology change of the silicon surface induced by Ar ion beam sputtering

It is well known that low and medium energy ion sputtering may induce a fabrication of periodic nanoscale structures on an irradiated surface [1]. Depending on the sputtered substrate characteristics and sputtering conditions, different types of nanoscale structures such as ripples, nanoholes and nanodots can grow on a target during ion beam sputtering [2–6]. These patterns have been found on b...

Simulating discrete models of pattern formation by ion beam sputtering.

A class of simple, (2+1)-dimensional, discrete models is reviewed, which allow us to study the evolution of surface patterns on solid substrates during ion beam sputtering (IBS). The models are based on the same assumptions about the erosion process as the existing continuum theories. Several distinct physical mechanisms of surface diffusion are added, which allow us to study the interplay of e...

Surface Morphology Evolution of GaAs by Low Energy Ion Sputtering

Low energy Ar ion sputtering, typically below 1,200 eV, of GaAs at normal beam incident angle is investigated. Surface morphology development with respect to varying energy is analyzed and discussed. Dot-like patterns in the nanometer scale are obtained above 600 eV. As the energy approaches upper eV range regular dots have evolved. The energy dependent dot evolution is evaluated based on solut...

Effect of surface morphology on the sputtering yields. I. Ion sputtering from self-affine surfaces

As extensive experimental studies have shown, under certain conditions, ion bombardment of solid targets induces a random (self-affine) morphology on the ion-eroded surfaces. The rough morphology development is known to cause substantial variations in the sputtering yields. In this article, we present a theoretical model describing the sputter yields from random, self-affine surfaces subject to...

Effect of surface morphology on the sputtering yields. II. Ion sputtering from rippled surfaces

Off-normal ion bombardment of solid targets with energetic particles often leads to development of periodically modulated structures on the surfaces of eroded materials. Ion-induced surface roughening, in its turn, causes sputtering yield changes. We report on a comprehensive theoretical study of the effect of rippled surface morphology on the sputtering yields. The yield is computed as a funct...
