ESR Characteristics of Cubic Boron Nitride Crystals

Abstract

ABSTRACTElectron spin resonance (ESR) spectrum have been used to study undoped cubic boron nitride crystals. The results show that the peak-to-peak width of the ESR signal is 27×10-4 T and the g-value is 2.00248, the spin density N s is 2.8×1015 cm-3, it is considered that the ESR signal is originated from the nitrogen dangling bond. Raman spectrum measurements have been also carried out, the peak positions are at 1054 cm-1 and 1306 cm-1.
