Аннотация: The explosive evaporation of a fullerene mixture in a vacuum of ∼10−2 Pa during the contraction of a 1-kW hollow electron beam into a spot on a substrate in a time of 0.1–1 s is considered. A comparative analysis of the Raman spectra and the absorption electron spectra of a starting fullerene mixture powder and the vapor condensates shows that the evaporation of C60 and C70 fullerenes proceeds without breaking C–C covalent bonds.

Заглавие : Thin fullerene-containing films synthesized by ion beam sputtering of fullerene mixtures with doping additives in vacuum
Место публикации : Tech. Phys. Lett.: AMER INST PHYSICS, 2005. - Vol. 31, Is. 12. - P1022-1025. - ISSN 1063-7850, DOI 10.1134/1.2150887

Аннотация: A new approach to the synthesis of films containing fullerenes and doping elements is described. It is suggested that a cluster mechanism of the target sputtering by accelerated ions makes possible the deposition of fullerenes on a substrate with a certain probability for dopant atoms being introduced into the cavities of fullerene molecules and a higher probability of their occurrence between fullerene molecules. The proposed method has been experimentally implemented by using an Ar+ ion beam to sputter C-60 /C-70 fullerene mixtures (synthesized in a plasmachemical reactor at a pressure of 10(5) Pa) pressed into disk targets with a doping element (Fe, Na, B, Gd, or Se). The ion beam sputtering of dopant-containing fullerene mixtures in a vacuum of similar to 10(-2) Pa allowed micron-thick films containing C-60 and C-70 fullerenes and the corresponding dopant element (Fe, Na, B, Gd, or Se) to be grown on quartz substrates.

Заглавие : Fullerene films deposited by evaporation in vacuum using spot-focused annular electron beam
Место публикации : Tech. Phys. Lett.: AMER INST PHYSICS, 2005. - Vol. 31, Is. 12. - P1036-1038. - ISSN 1063-7850, DOI 10.1134/1.2150891

Аннотация: A rapidly focused annular electron beam can provide for the effective evaporation of a fullerene mixture in a vacuum of similar to 10(-2) Pa. A 1-kW beam focused into a spot within 0.1-1 s produces explosive evaporation of a fullerene target at an extremely high efficiency of heating. A comparison of the Raman and electronic absorption spectra of the initial fullerene powder and a film deposited upon its evaporation shows that C-60 and C-70 fullerenes are evaporated without rupture of C-C covalent bonds. The electron beam evaporation in vacuum has been successfully used to obtain fullerene films on substrates with an area of similar to 0.1 m(2). (C) 2005 Pleiades Publishing, Inc.
