Abstract

Based on X-ray diffraction data obtained for thin polycrystalline CdS films and computer simulation using the Debye formula in the framework of the DISCUS program, it has been established that the location of close-packed Cd planes in CdS nanoparticles is disordered. The absence of strict periodicity of the atomic structure in the presence of close packing, with the mutual tetrahedral environment of Cd and S atoms, is a special feature of CdS in the nanostate. The average lattice of a disordered close-packed structure is described by space group P6 with parameters of the unit cell a = 0.236 and c =0.334 nm and a degree of occupation of crystal-lattice sites of 1/3.
