Gan Nanorod Arrays Formed By Ion Beam Implantation

US Patent:
2010025, Oct 7, 2010
Filed:
Jun 29, 2006
Appl. No.:
11/993677
Inventors:
Wei-Kan Chu - Pearland TX, US
Hye-Won Seo - Houston TX, US
Quark Y. Chen - Houston TX, US
Li-Wei Tu - Houston TX, US
Xuemei Wang - Houston TX, US
Assignee:
UNIVERSITY OF HOUSTON - Houston TX
International Classification:
H01L 29/66
H01L 21/20
US Classification:
257 11, 438506, 257 9, 257E2109, 257E29168, 977762
Abstract:
A method of preparing nanorod arrays using ion beam implantation is described that includes defining a pattern on a substrate and then implanting ions into the substrate using ion beam implantation. Next, a thin film is deposited on the substrate. During film growth, nanotrenches form and catalyze the formation of nanorods through capillary condensation. The resulting nanorods are aligned with the supporting matrix and are free from lattice and thermal strain effect. The density, size, and aspect ratios of the nanorods can be varied by changing the ion beam implantation and thin film growth conditions resulting in control of emission efficiency.

Vibration-Free Levitated Platform

US Patent:
5726512, Mar 10, 1998
Filed:
Oct 4, 1996
Appl. No.:
8/726147
Inventors:
Wei-Kan Chu - Pearland TX
Quark Yung-Sung Chen - Houston TX
Mark Alan Lamb - Tempe AZ
Chase Kenyon McMichael - Houston TX
Ignatius S. T. Tsong - Tempe AZ
Assignee:
The University of Houston System - Houston TX
International Classification:
B60L 1304
H02K 709
US Classification:
310 905
Abstract:
An isolation system for isolating a first object from vibrations from a second object. Such vibrations will have three orthogonal components, one oriented along a line between the objects, and two oriented 90. degree. apart in a plane normal to that line. The system includes three superconductor/magnet stages, each stage designed to extinguish one of the orthogonal components.

Magnet-Superconductor Flywheel And Levitation Systems

US Patent:
5831362, Nov 3, 1998
Filed:
Jul 16, 1997
Appl. No.:
8/895387
Inventors:
Wei-Kan Chu - Pearland TX
Quark Yung-Sung Chen - Houston TX
Harold Zule Xia - Houston TX
Mark Alan Lamb - Houston TX
Rodger Sheldon Cooley - Houston TX
Chase Kenyon McMichael - Houston TX
Assignee:
The University of Houston - Houston TX
International Classification:
H02K 709
US Classification:
310 905
Abstract:
Disclosed is a flywheel system for storing kinetic energy which utilizes a high temperature superconductor/magnet system for the flywheel bearings. The flywheel includes a first magnet, and having a ring magnet defining an opening. The levitation system includes a magnet for attractively interacting with first flywheel magnet, with a high temperature superconductor interposed between them, and further includes a magnet system for repulsively interacting with and partially inserted into the ring magnet.

Satellite Angular Momentum Control System Using Magnet-Superconductor Flywheels

US Patent:
6231011, May 15, 2001
Filed:
Nov 2, 1998
Appl. No.:
9/184914
Inventors:
Wei-Kan Chu - Pearland TX
Ki Bui Ma - Jersey Village TX
Quark Yung-Sung Chen - Houston TX
Eujeong Lee - Houston TX
Yevgeniy Postrekhin - Houston TX
Assignee:
University of Houston System - Houston TX
International Classification:
B64G 128
US Classification:
244165
Abstract:
A torque/reactive momentum wheel control system for use in satellites for dynamic attitude maintenance and alteration where the flywheel of each momentum wheel is levitated by a high-temperature superconducting element repulsively interacting with permanent magnets in the flywheel. The spin rate (rpm) of the flywheel being controlled by either an active magneto or electromagneto drive system. Each momentum wheel is cooled by a cryo-cooler and can have a total weight of about 10 Kg to a fraction of 1 Kg and delivering 3. 5 Js with less than 1 W loss.
