Cubic boron nitride and its gas phase synthesis method

Cubic boron nitride which is obtained from a gas phase without using an ultra-high pressure and which distinctly shows, in the Raman spectrum, either characteristic scattering by phonon of an optical longitudinal wave mode at 1305±15 cm-1 or characteristic scattering by phonon of an optical transver...

Zusammenfassung:Cubic boron nitride which is obtained from a gas phase without using an ultra-high pressure and which distinctly shows, in the Raman spectrum, either characteristic scattering by phonon of an optical longitudinal wave mode at 1305±15 cm-1 or characteristic scattering by phonon of an optical transverse wave mode at 1056±15 cm-1, or both characteristic scatterings.
