    摘要: The invention provides a method for manufacturing a gallium nitride-based semiconductor device having low-density crystalline defects and high-quality crystalinity. In the manufacturing method according to the invention, first, a gallium oxide substrate is prepared. Then, a surface of the gallium oxide substrate is modified into a nitride via physical or chemical pretreatment to form a surface nitride layer having Ga—N bonding. Finally, gallium nitride-based semiconductor layer is formed on the surface nitride layer.

    摘要: A two-layer nanotape that includes a nanoribbon substrate and an oxide that is epitaxially deposited on a flat surface of the nanoribbon substrate is described. A method for making the nanotape that includes providing plural substrates and placing the substrates in a quartz tube is also described. The oxide is deposited on the substrate using a pulsed laser ablation deposition process. The nanoribbons can be made from materials such as SnO2, ZnO, MgO, Al2O3, Si, GaN, or CdS. Also, the sintered oxide target can be made from materials such as TiO2, transition metal doped TiO2 (e.g., CO0.05Ti0.95O2), BaTiO3, ZnO, transition metal doped ZnO (e.g., Mn0.1Zn0.9O and Ni0.1Zn0.9O), LaMnO3, BaTiO3, PbTiO3, YBa2Cu3Oz, or SrCu2O2 and other p-type oxides. Additionally, temperature sensitive nanoribbon/metal bilayers and their method of fabrication by thermal evaporation are described. Metals such as Cu, Au, Ti, Al, Pt, Ni and others can be deposited on top of the nanoribbon surface. Such devices bend significantly as a function of temperature and are suitable as, for example, thermally activated nanoscale actuators.
