Superconductivity in CVD diamond films.
A beautiful jewel of diamond is insulator. However, boron doping can induce semiconductive, metallic and superconducting properties in diamond. When the boron concentration is tuned over 3 × 10(20) cm(-3), diamonds enter the metallic region and show superconductivity at low temperatures. The metal-insulator transition and superconductivity are analyzed using ARPES, XAS, NMR, IXS, transport and ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Analysis of the Surface Morphology of Cvd-grown Diamond Films with X-ray Diffraction
In this study the influence of the addition of nitrogen during growth of diamond films is determined using small-spot X-ray diffraction techniques and compared with the morphological structure. Phase identification showed the presence of crystalline molybdenum carbide at the interface, as well as the incorporation of a small amount of non-diamond carbon throughout the diamond layer. The pole fi...
متن کاملCemented Carbides – a Success Story
After WW2, a huge market opened in the growing economies and cemented carbides contributed as tool materials and construction parts to their industrial development. Today, cemented carbides are the workhorses in all areas of the manufacturing industries: no factory without cemented carbide tools; no production of glass bottles, aluminium cans or plastic tubes which has not benefited from these ...
متن کاملUV photoemission efficiency of polycrystalline CVD diamond films
The absolute quantum efficiency of polycrystalline diamond films grown on silicon substrates by chemical vapor deposition (CVD) is reported in the range of 25–200 nm. The efficiency of boron-doped and hydrogen-activated by microwave plasma reflective photocathodes peaked at 37% at 40 nm with the sensitivity cutoff observed at ~190 nm. We confirmed that hydrogen activation is relatively stable i...
