Peculiarities of fullerenes condensation
from molecular beam in vacuum

Keywords: fullerenes, sublimation, condensation, carbon allotropes, surface morphology, Raman spectroscopy.

There was investigated С₆₀ fullerenes condensation in vacuum on unheated Si, GaAs, isinglass stone substrates. There were used atomic-force microscopy, Raman scattering and measurement of mechanical stresses in films. It is established that the С₆₀ molecule can decay on the substrates with the formation of other carbon structures in the condensate without supplementary physical effects on the sublimated beam in «evaporator — substrate» space. The possibility was found to increase the grain size and reduce the mechanical stresses in the condensate.
