Investigation on Ge surface diffusion via growing Ge quantum dots on top of Si pillars
We report on a simple and intuitionistic experimental method to quantitatively measure surface diffusion lengths of Ge adatoms on Si(001) substrates and its activation energy Ea, which is achieved by growing Ge quantum dots (QDs) on top surfaces of Si pillars with different radii and taking an advan...
