Abstract

Decoration of nitrogen vacancies by oxygen atoms has been studied by near-edge x-ray absorption fine structure (NEXAFS) in several boron nitride (BN) structures, including bamboo-like and multi-walled BN nanotubes. 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.
