From: Investigations of Vacancy Structures Related to Their Growth in h-BN Sheet
Optimized structures of a V21B+15N vacancy structure with possible missing positions of BN-pair and b–g V22B+16N vacancy structures after a BN-pair missing at specific positions. The dotted circles with numbering in a represent possible positions of BN-pair missing. The positions with numbering 1 to 6 is denoted as b corner-1, c face-1, d face-2, e face-3, f face-4, and g corner-2 missing structures, respectively
