Decoration of nitrogen vacancies by oxygen atoms in boron nitride nanotubes

Abstract

Decoration of nitrogen vacancies by oxygen atoms has been studied by near-edge X-ray absorption fine structure (NEXAFS) around B K-edge in several boron nitride (BN) structures, including bamboo-like and multi-walled BN nanotubes. Breaking of B–N bonds and formation of nitrogen vacancies under low-energy ion bombardment reduces oxidation resistance of BN structures and promotes an efficient oxygen-healing mechanism, in full agreement with some recent theoretical predictions. The formation of mixed O–B–N and B–O bonds is clearly identified by well-resolved peaks in NEXAFS spectra of excited boron atoms.
