Presented are the results of investigation of the surface morphology and fine structure of thick (25…50 μm) carbon films, produced from a vapor phase by using the electron beam technology of evaporation of graphite and subsequent condensation in vacuum. The structures of carbon films were investigated in a wide range of condensation temperatures 100…1500 ^oC. The integrated examinations by the methods of scanning and transmission electron microscopy showed that the substrate temperature (condensation) has a main effect on the carbon condensate formation. With the growth of condensation temperature the dimensional characteristics of crystallites, forming the carbon film, are increased from 2…4 up to 20…80 μm. It was found that the internal structure of crystallites within the whole temperature range is remained almost unchanged and consists of aggregates of 0.015…0.030 ?m size, which have a nanodimensional structure and consist of clusters of 3…6 nm size.
