The (0001) surface of Sb2Te3 layered chalcogenide crystal was used for self-organizing of deposited indium nanostructures' arrays during solid state dewetting procedure. The study found that the shape and spatial arrangement of the nanostructures were consistent with the surface lattice symmetry.
Sb2Te3 layered chalcogenide crystal's (0001) surface was applied for self-organizing of deposited indium nanostructures' arrays while solid state dewetting procedure. Sb2Te3 samples were characterized by XRD, XPS, LEED and STM/STS. STM shows that shape and spatial arrangement of indium induced 0D nanostructures are consistent with the surface lattice symmetry. The fractal analysis of STM images of the (0001) Sb2Te3 and (0001) InSe surfaces, which are similar in symmetry, shows that distribution in size of indium nanostructures are almost the same under commensurate experimental conditions. The STS reveals correlation between indium coverage and quantity of DOS within energy gap of Sb2Te3.
