Abstract

The long range ordering of epitaxial semiconductor quantum dots is investigated using several crystal growth techniques on prepatterned substrates. We have developed two nucleation site control techniques: one which uses localized surface chemical potential engineering and one which uses localized surface strain engineering. We present experimental results that demonstrate the ability to create ordered quantum dot lattices and discuss the different mechanisms involved in the long range ordering of quantum dots.
