The results of complex experimental study of In4Se3 layered crystal cleavage surfaces by methods of low energy electron diffraction (LEED), scanning tunneling microscopy and spectroscopy (STM/STS) and atomic force microscopy and spectroscopy (AFM/AFS) are presented. System study of nanostructured semiconductor anisotropic matrices, such as cleavage (100) surfaces of In4Se3 was conducted with the purpose to obtain nanosystems on them as substrate. The influence of different kinds of defects (point, linear, macro defects) of interlayer (100) In4Se3 layered crystal cleavage surfaces on their topography and local density of surface electronic states (LDOS) and their electron energy structure was studied. It has been established the significant influence of different defect's concentrations on LDOS and on electron-energy structure of interlayer cleavage surfaces for all layered crystals.
