Abstract

The novel technique of the formation of metal nanoclusters embedded into solid film is presented. The bombardment of the amorphous 5 nm thick two-component film formed by pulsed laser co-deposition of Au and C atoms, by fast electrons in the column of the transmission electron microscope is demonstrated to result in the nucleation and growth of Au nanoclusters embedded in carbon film. The proposed mechanism of thin film heating under the electron beam allows the evaluation of the local film temperature Т~100 С. The growth of nanoclusters can be qualitatively described in the frames of LifshitzSlyozov mechanism..
