The features of InAs quantum dots obtained on GaAs(001) single-crystal substrates by ion-beam sputtering were investigated. It has been shown that in the range of ion energies of 150 to 200 eV at a temperature of 500 °C and a beam current of 120 µA InAs quantum dots with average dimensions below 15 nm and a surface density of 1011 cm-2 are formed. The technique of controlled doping of InAs/GaAs...
Ti-based MXenes: Preparation by Ion Beam Sputtering and Microstructural Evolution by Ion Irradiation
Titanium nitride thin films were grown on 304 stainless steel substrates at various nitrogen/argon flow ratios by ion beam sputtering (IBS) technique. The current research is a follow up study on the influence of gas ratio on structural and corrosion properties in the TiN coated 304 stainless steel. Film structural identification of phases was performed using X-ray diffractometry (XRD). Sca...
The classical theory of ion beam sputtering predicts the instability of a flat surface to uniform ion irradiation at any incidence angle. We relax the assumption of the classical theory that the average surface erosion rate is determined by a Gaussian response function representing the effect of the collision cascade and consider the surface dynamics for other physically-motivated response func...
In this paper, selection of proper method for titanium coating on copper substrate is studied to construct nuclear targets for neutron production in particle accelerators. In order to construct such targets, it is necessary to deposit, through the coating methods, the proper coating of titanium on copper. Among different coating methods, ion plating and sputtering, due to the high coating yield...
