Description
Summary:The structure of unsupported epitaxial films of С₆₀-Bi composite with hcp lattice has been studied after irradiation by 100 keV electron beam in the electron microscope column. А short-time irradiation of the film by electrons at the average current density of 40 А/cm² results in the composite evaporation in the beam central area. In the film boundary region, pores are formed of dimensions well correlated with the nanodimensional areas of the segregated bismuth. The electron bombardment results in reduced interplanar spacings depending on the plane system index and the irradiation intensity. А qualitative mechanism of pore formation has been proposed.
