Mechanical properties and failure behaviors of the interface of hybrid graphene/hexagonal boron nitride sheets.

ABSTRACT: Hybrid graphene/h-BN sheet has been fabricated recently and verified to possess unusual physical properties. During the growth process, defects such as vacancies are unavoidably present at the interface between graphene and h-BN. In the present work, typical vacancy defects, which were located at the interface between graphene and h-BN, were studied by density functional theory. The interface structure, mechanical and electronic properties, and failure behavior of the hybrid graphene/h-BN sheet were investigated and compared. The results showed that the formation energy of the defective graphene/h-BN interface basically increased with increasing inflection angles. However, Young's modulus for all graphene/h-BN systems studied decreased with the increase in inflection angles. The intrinsic
