Abstract

The influence of charged sapphire steps on gold, ZnO, and CdTe nanoislands formed on the surface of Al2O3 under vacuum condensation is discussed. Electrically active surface steps are interpreted as a particular case of electrical boundaries existing on dielectric crystal surfaces. The interaction between an uncharged dome-shaped nanoisland and a uniformly charged step is estimated.
