1. A process for producing a nano-structure which is comprised of a matrix comprised of silicon, germanium, or silicon-germanium and cylindrical portions comprised of aluminum not larger than 30 nm in diameter and having the longitudinal direction perpendicular to a substrate, the process comprising the step of forming a mixed film of Alx(SiyGe1-y)1-x (0.3≤X≤0.8, 0≤Y≤1) on the substrate by using aluminum and silicon, aluminum and germanium, or aluminum, silicon and germanium as the source materials, at a film-forming rate of not higher than 150 nm/min.
