Abstract
The present invention provides a method for producing layered aluminum fine particles, and applications to single electron tunneling quantum devices, and the present invention further relates to a method for producing spherical metallic aluminum fine particles (layered aluminum fine particles), characterized in that metallic aluminum is supplied into a mixed gas of helium and 1×10,to 3×10,torr water vapor by sputtering induced by argon gas discharge to generate aggregates, after which this product is released into a vacuum to generate single crystals in which the surface layer is covered with alumina.
