The crystal structure of AAh BN. (a) A crystal unit of AAh BN assigned as orthorhombic (No. 31, Pm21). (b) A simulated ED pattern of AAh BN. Strong (020) and (200) spots result in a diagonal pattern, although relatively weak (110) and (220) spots appear. (c) A simulated HRTEM image of AAh BN. Linear lattices, corresponding to (020), are evident.
