Abstract
The results of an experimental study of nickel nanostructures formation in NiхInSe intercalates are presented. The surface topography and crystallography study data and also electron energy structure of interlayer (0001) cleavage surface of InSe layered crystals, equilibrium thermodynamically intercalated by nickel (Ni3dInSe intercalates) were obtained by methods of scanning tunneling microscopy and scanning tunneling spectroscopy (STM / STS) and also low energy electrons diffraction (LEED). It is determined that nickel is placed in the interlayer gaps of NiхInSe intercalates and, therefore, is observed at the interlayer (0001) cleavage surfaces thus forming Ni3d/InSe(Ni)(0001) nanosystem and occurs in the fine - dispersed phase of nickel metal clusters on the (0001) cleavage surface. The concentrations of nickel metal clusters on the cleavage (0001) surfaces in Ni0.75InSe intercalates are estimated at the level of 0.8–1.25 % by STS and computer analysis method of the current-voltage characteristics in Ni3d/InSe(Ni)(0001) nanosystems.
