Abstract
This paper presents the results of growing chalcogenide nanowires of Sb2Te3 with a phase transition and a controlled diameter on Si substrates by the chemical vapor deposition method using an Au catalyst. In addition to the size of the Au catalyst, the amount of the initial Sb2Te3 powder is also used to control the diameter of Sb2Te3 nanowires. The diameter of the Sb2Te3 nanowires clearly increases with both the size of the Au catalyst and the amount of the Sb2Te3 powder. By effectively controlling the size of Au nanoparticles and the amount of the Sb2Te3 powder, the diameter of the Sb2Te3 nanowires can be controlled in a wide range from 145 to 275 nm. The influence of the size of Au nanoparticles and the amount of the Sb2Te3 powder on the diameter of the Sb2Te3 nanowires is revealed in terms of supersaturation, based in detail on the Gibbs–Thomson effect.
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.
