Abstract
We have developed a technique for the synthesis of size-selected, GaAs,epitaxial nano-whiskers, grown on a crystalline substrate. As catalysts, we used size-selected goldaerosol particles, which enabled us to fully vary the surface coverage independently of the whisker diameter. The whiskers were rod shaped, with a uniform diameter between 10 and 50 nm, correlated to the size of the catalytic seed. Furthermore, by the use of nano-manipulation of the aerosol particles by means of atomic force microscopy, we can nucleate individual nano-whiskers in a controlled manner at specific positions on a substrate with accuracy on the nm level.Keywords
