Abstract

The present invention presents a process for preparing a quantum dot array comprising at least the steps of: (a) providing a crystalline semiconductor substrate surface; (b) depositing quantum dots on the said substrate surface by a process of successive ionic layer adsorption and reaction (SILAR). The steps can be repeated to build up a quantum dot superlattice structure.
