Thin Semiconductor Films of Fullerene C70 Nanoaggregates on the Surface of a Plane Glass Substrate

Abstract

It was shown for the first time that, in the volume of an evaporating drop of a fullerene C₇₀ solution in toluene located on the surface of a glass substrate, the self-organization of C₇₀ molecules occurs and crystalline nC₇₀ nanoaggregates of a spherical shape are synthesized. Films of nC₇₀ nanoaggregates are deposited on a plane surface of a glass substrate. The physical mechanism of the self-organization of C₇₀ molecules and the formation of large nC₇₀ nanoaggregates are proposed, namely, Ostwald ripening, according to which relatively large nC₇₀ nanoaggregates grow through smaller ones. The possibility of using thin films as solar transducers is discussed.
