چکیده :
Two-dimensional hexagonal boron nitride (h-BN) features a hexagonal lattice structure and special electrical and thermal properties that make it attractive for a variety of applications, including resistive switching memory and neuromorphic computing. Although numerous experimental and theoretical studies have been carried out in this area, it is still unclear how exactly the layers are switched on and off. In this study we investigate the dynamics of defects in a multilayer h-BN, which is sandwiched between two Ni electrodes. The effects of different electric fields were studied using the Reax force field (Reaxff) and molecular dynamics simulation. It has been discovered that certain defects, such as Stone-Wales defects (SW) and multiple vacancies arising from nitrogen vacancies (VN) and boron vacancies (VB), play an important role in the formation of conductive filaments and bridges between layers. These bridges have a significant impact on the electrical and switching properties of multilayer h-BN.
