Abstract: The present invention provides a process for forming electrical contacts to a molecular layer in a nanoscale device, the nanoscale device, and a method of manufacturing an integrated circuit comprise such devices. The process includes coating a surface of a stamp with a metal layer and forming an attached layer of anchored molecules by coupling first ends of the anchored molecules to a conductive or semiconductive substrate. The process also includes placing the metal layer in contact with the attached layer of anchored molecules such that the metal layer chemically bonds to free ends of the anchored molecules. The resulting devices produced have superior reliability as compared to conventional prepared devices.

Abstract: An apparatus includes a crystalline substrate having a top surface, a crystalline semiconductor layer located on the top surface, and a plurality of dielectric regions. The crystalline semiconductor layer includes group III-nitride and has first and second surfaces. The first surface is in contact with the top surface. The second surface is separated from the top surface by semiconductor of the crystalline semiconductor layer. The dielectric regions are located on the second surface. Each dielectric region is distant from the other dielectric regions and covers an end of an associated lattice defect. Each lattice defect threads the crystalline semiconductor layer.

Abstract: One method includes epitaxially growing a layer of group III-nitride semiconductor under growth conditions that cause a growth surface to be rough. The method also includes performing an epitaxial growth of a second layer of group III-nitride semiconductor on the first layer under growth conditions that cause the growth surface to become smooth. The two-step growth produces a lower density of threading defects. Another method includes epitaxially growing a layer of group III-nitride semiconductor on a lattice-mismatched crystalline substrate and then, chemically treating a growth surface of the layer to selectively electrically passivate defects that thread the layer.
