Abstract: A method for growth and fabrication of semipolar (Ga, Al, In, B)N thin films, heterostructures, and devices, comprising identifying desired material properties for a particular device application, selecting a semipolar growth orientation based on the desired material properties, selecting a suitable substrate for growth of the selected semipolar growth orientation, growing a planar semipolar (Ga, Al, In, B)N template or nucleation layer on the substrate, and growing the semipolar (Ga, Al, In, B)N thin films, heterostructures or devices on the planar semipolar (Ga, Al, In, B)N template or nucleation layer. The method results in a large area of the semipolar (Ga, Al, In, B)N thin films, heterostructures, and devices being parallel to the substrate surface.

Publication number: 20110041966
Abstract: A Co-based alloy having a fundamental composition of Co—Al binary system containing 3-15% Al and having lamellar structure wherein f.c.c. structure ?-phase and ?(B2)-phase are superimposed on each other in layers, which Co-based alloy is modified so as to have a porous surface layer region effective for chemical retaining capability, sustained release, biocompatibility, etc. through selective removal of either the ?-phase or the ?-phase from the surface layer. As a third component, at least one member selected from among Ni, Fe, Mn, Ga, Cr, V, Ti, Mo, Nb, Zr, W, Ta, Hf, Si, Rh, Pd, Ir, Pt, Au, B, C and P may be contained in a total amount of 0.001 to 60%.
