Abstract
Metallic quantum dots coated by amorphous carbon were produced by simultaneous evaporation of carbon and metal in Ar gas at 13 kPa. Carbon-coated Ag, Fe and Au dots with a size of 2–20 nm can be easily obtained. In the present experimental system, C60 crystals were also observed. The quantum dots included in C60 crystals have been indicated. The growth of carbon-coated metallic dots has been discussed on the assumption of the formation of a metallic liquid drop near the evaporation source.
