Properties of InAs Quantum Dots on Silicon(001) and (111)
Abstract
The self assembled formation of InAs Quantum Dots (QDs) on silicon has been studied by RHEED, AFM, Raman and TEM. On Si(001) up to 10(exp11)cm(-2) InAs QDs can either be grown in a conventional growth mode, or by utilizing a postgrowth dewetting transition at decreasing substrate temperatures. On Si( 111) instead, QDs only form on an As-passivated surface. Otherwise InAs grows in large 2D clusters.
