Dramatically enhanced self-assembly of GeSi quantum dots with superior photoluminescence induced by the substrate misorientation
A dramatically enhanced self-assembly of GeSi quantum dots (QDs) is disclosed on slightly miscut Si (001) substrates, leading to extremely dense QDs and even a growth mode transition. The inherent mechanism is addressed in combination of the thermodynamics and the growth kinetics both affected by st...
