6583436 Strain-engineered, self-assembled, semiconductor quantum dot lattices June 24, 2003
A method for growing strain-engineered, self-assembled, semiconductor quantum dots (QDs) into ordered lattices. The nucleation and positioning of QDs into lattices is achieved using a periodic sub-surface lattice built-up on a substrate, stressor layer, and spacer layer. The unit cell
6541788 Mid infrared and near infrared light upconverter using self-assembled quantum dots April 1, 2003
A method and device for converting light from a first wavelength to a second wavelength. The method comprises the steps of exciting an electron in a quantum dot with an incident infrared photon having the first wavelength, the excited electron having a first energy, tunneling the exc
6307241 Integrable ferromagnets for high density storage October 23, 2001
Submicron ferromagnets, of selected size and spacing, are introduced into semiconductor by means of ion implantation and subsequent heat treatments. The resulting semiconductor contains ferromagnets at high density and which exhibit Curie temperatures exceeding room temperature. The
5192709 Nanoscale modulation doping method March 9, 1993
A method for modulation doping of semiconductor heterostructures includes forming a semiconductor heterostructure comprising a substrate layer, a narrow band-gap quantum well layer, and a donor implantation layer. A focused ion beam writes across the surface of the donor implantation
5013683 Method for growing tilted superlattices May 7, 1991
A method for growing a superlattice structure on a substrate. First, a periodic array of monoatomic surface steps are created on the surface of the substrate at an area to have the superlattice structure grown thereon. There is apparatus for creating a beam of a material being input ther
