WebSep 7, 2024 · cubic boron nitride; magnetron sputtering; gas composition; nucleation; substrate bias 1. Introduction Cubic boron nitride (c-BN), an analog of diamond, exhibits many outstanding properties, such as extreme hardness, wide band gap, negative electron affinity, and high thermal conductivity. WebJul 15, 1994 · Using Brillouin scattering the three independent elastic stiffness constants cij of single‐crystal cubic boron nitride have been measured: c11=820, c12=190, and c44=480 GPa. The resulting bulk modulus, 400 GPa, is in reasonable agreement with two independent determinations obtained from x‐ray measurements in a diamond anvil cell. …

WebPossible candidates are diamond or cubic boron nitride (cBN)-based ceramic composites. Because of the metastability of diamond and cBN under normal pressure and higher temperatures, cBN–ceramic and diamond–ceramic matrix composites are mostly produced under high-pressure conditions up to now. This results in restrictions in geometry and costs.
