  • Patent number: 11001497
    Abstract: Topological insulators, such as single-crystal Bi2Se3 nanowires, can be used as the conduction channel in high-performance transistors, a basic circuit building block. Such transistors exhibit current-voltage characteristics superior to semiconductor nanowire transistors, including sharp turn-on, nearly zero cutoff current, very large On/Off current ratio, and well-saturated output current. The metallic electron transport at the surface with good effective mobility can be effectively separated from the conduction of the bulk topological insulator and adjusted by field effect at a small gate voltage. Topological insulators, such as Bi2Se3, also have a magneto-electric effect that causes transistor threshold voltage shifts with external magnetic field. These properties are desirable for numerous microelectronic and nanoelectronic circuitry applications, among other applications.

The F-DLC film has an element ratio (F/(F+C)) of 17% to 72% and a nanoindentation hardness of 2,000 MPa to 16,000 MPa. This maintains wear resistance and close contact, and obtains an antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration. The F-DLC film does not necessarily need to cover the entire outermost surface of the base material but may be disposed in a mottled pattern.

    Abstract: A carbon/carbon brake disk is provided. The carbon/carbon brake disk may comprise a carbon fiber, wherein the carbon fiber is formed into a fibrous network, wherein the fibrous network comprises carbon deposited therein. The carbon fiber may undergo a FHT process, wherein micro-cracks are disposed in the carbon fiber. In various embodiments, the micro-cracks may be at least partially filled with un-heat-treated carbon via a final CVD process, wherein the final CVD process is performed at a temperature in the range of up to about 1,000° C. (1,832° F.) for a duration in the range from about 20 hours to about 100 hours. In various embodiments, the un-heat-treated carbon may be configured to prevent oxygen, moisture, and/or oxidation protection systems (OPS) chemicals from penetrating the carbon/carbon brake disk. In various embodiments, the final CVI/CVD process may be configured to increase the wear life of the carbon/carbon brake disk.

  • Patent number: 10651034
    Abstract: A method of forming an epitaxial layer on a substrate such as a sapphire wafer that does not readily absorb thermal radiation. The method includes coating a first side surface of the substrate with an energy-absorbing opaque material. The opaque material forms a thermally absorptive coating on the substrate. The coated substrate may be heated to remove contaminants from the thermally absorptive coating. The coated substrate is positioned in a vacuum deposition chamber and heated by directing radiative energy onto the thermally absorptive coating. An epitaxial layer such as GaN or SiGe is formed on a second side surface of the substrate opposite the thermally absorptive coating.
