    A CVD Diamond-Based Photodetector for the Visible and Near

    A photodetector for the visible and near-IR spectral range has been created on the basis of a chemical- vapor-deposited diamond modulation-doped with boron. The detected electromagnetic radiation is absorbed in a thin Cr (7 nm)–Au (5.5 nm) bimetallic sublayer deposited on the surface of a modulationdoped diamond film comprising a highly doped (up to 5 × 1019 cm–3) 3-nm-thick delta-layer

    The present article presents the results of triboengineering tests of polycrystalline diamonds deposited chemically from the gaseous phase together with intermetallides of the Al-Ti system. The conditions are determined when the diamond wears intensively; these conditions appear due to the use of a metallic catalysis precursor as a counterbody. The study results are expected to contributed to

    High quality MPACVD diamond single crystal growth: high

    CVD diamond is obtained from gaseous precursors essentially constituted of carbon and hydrogen. Oxygen can also be added in the gas phase, either directly, or through the carbon species used, and Bachmann et al [] have established a diagram in C–H–O space defining the various domains of diamond synthesis as a function of the concentrations of each of the elements in the gas phase.

    Comparison of the hole mobility in undoped and boron-doped

    The drift mobility of nonequilibrium holes injected in undoped polycrystalline diamond films was determined, by a transit-time technique, as ca. 10−3 cm2/(V s). This hole mobility is three orders of magnitude lower than the “equilibrium” mobility in boron-doped diamond films [0.1–1 cm2/(V s)], determined from the films' dc conductivity. This difference is explained by the effect of a
