Preparation of Semiconducting Cubic Boron Nitride

The Journal of Chemical Physics, 1962
Semiconducting crystals of cubic BN may be prepared at high pressures and temperatures by adding small amounts of selected impurities to the synthesis mixture (hexagonal boron nitride plus lithium or magnesium nitride). P-type crystals, blue in color, can be prepared by adding Be; they may have resistivities of about 103 ohm-cm and activation energies ...

Deposition mechanism of cubic boron nitride

Diamond and Related Materials, 1996
Abstract The ion assisted deposition of cubic BN (c-BN) is argued to occur by subplantation, in which low energy ions are implanted below the surface to increase the local density. The situation differs from the case of tetrahedral amorphous carbon (ta-C), because the heteropolar bonding of BN stabilises its crystalline over the amorphous phase. This

Luminescence centers in cubic boron nitride

Journal of Applied Spectroscopy, 2007
Complex and multiband photoluminescence spectra for GB and HBN centers in single crystals of cubic boron nitride (cBN) were recorded in the wavelength ranges 385–400 nm and 365–395 nm and the nature of these centers was studied. The use of models involving resonance vibrations and strongly shifted configuration diagrams for the electronic ground state ...

Characterization of cubic boron nitride compacts

Materials Research Bulletin, 1986
Abstract c-BN compacts find extensive applications in machining and shaping of hard ferrous materials. These compacts are synthesized at high temperature and high pressure in the presence of suitable binders. A comparative study of c-BN compacts synthesized at the National Physical Laboratory, New Delhi and those obtained from three other sources ...
