Research of structure and conductivity of films systems C-60-Bi
The structure and conductivity of films of system C-60-Bi received is investigated with a joint deposition from two Knudsen's cells in vacuum similar to 5(.)10(-4) Pa on substrates from artificial mica. Is established that with temperature similar to 470K and ratio of density of flows of atoms Bi and molecules C-60 less than 0,5 in an interval of thickness 40-50 nm, grow of epitaxial single crystal films with close-packed hexagonal structure. Feature of the high-resolution electron microscopy images of condensates is the presence of irregular conglomerations of low concentrations bismuth is noted in the form of deposits 3-10 nm in size distributed across the volume of the film. The conductivity of films in a mode thermocycling was measured in an interval of temperatures 510-300K directly after of condensation without bleed-in of air in the vacuum chamber.
