Abstract: The present invention relates to a method for reproducibly forming a predetermined quantum dot structure and a device produced using same. A crystal facet of a substrate base is patterned for providing a predetermined portion of the crystal facet for subsequent predetermined crystal growth. A first growth material is deposited for crystallographically growing a predetermined mesa structure on the predetermined portion of the crystal facet. The mesa structure, which is a portion of the quantum dot structure, comprises predetermined low index side facets and a predetermined top surface. A second growth material for forming at least a quantum dot on the mesa structure is then deposited. The number, the lateral dimensions and the location of the at least a quantum dot is determined by the mesa structure. A sufficient amount of the second growth material is deposited such that a sufficient thickness for Straski-Krastinow growth of the second growth material on the top surface of the mesa structure is exceeded.
