摘要： A nano-scale device and method of fabrication provide a nanowire having (111) vertical sidewalls. The nano-scale device includes a semiconductor-on-insulator substrate polished in a [110] direction, the nanowire, and an electrical contact at opposite ends of the nanowire. The method includes wet etching a semiconductor layer of the semiconductor-on-insulator substrate to form the nanowire extending between a pair of islands in the semiconductor layer. The method further includes depositing an electrically conductive material on the pair of islands to form the electrical contacts. A nano-pn diode includes the nanowire as a first nano-electrode, a pn-junction vertically stacked on the nanowire, and a second nano-electrode on a (110) horizontal planar end of the pn-junction. The nano-pn diode may be fabricated in an array of the diodes on the semiconductor-on-insulator substrate.

摘要： An imprinting apparatus and method of fabrication provide a mold having a pattern for imprinting. The apparatus includes a semiconductor substrate polished in a [110] direction. The semiconductor substrate has a (110) horizontal planar surface and vertical sidewalls of a wet chemical etched trench. The sidewalls are aligned with and therefore are (111) vertical lattice planes of the semiconductor substrate. The semiconductor substrate includes a plurality of vertical structures between the sidewalls, wherein the vertical structures may be nano-scale spaced apart. The method includes wet etching a trench with spaced apart (111) vertical sidewalls in an exposed portion of the (110) horizontal surface of the semiconductor substrate along (111) vertical lattice planes. A chemical etching solution is used that etches the (111) vertical lattice planes slower than the (110) horizontal lattice plane. The method further includes forming the imprinting mold.

摘要： Embodiments of the present invention relate to a family of image-rotation prisms. Each image-rotation prism has the property that as an image-rotation prism is rotated, an image passing through the image-rotation prism rotates at twice the angular rate of the image-rotation prism. Embodiments of the present invention include optical systems that can be used for board-to-board communications and employ the image-rotation prisms to compensate for arbitrary axial rotations and misalignment of optical signals and can be used to direct optical signals output from transmitters on one board to particular detectors of a detector arrangement located on an adjacent board.
