“…[5][6][7][8] These values are close to the experimental values of graphene (Young's modulus of 1.0 TPa and breaking strength of 130 GPa). Due to their analogous crystal structures, atomically thin BN has many properties similar to those of graphene.…”

Atomically thin boron nitride (BN) is an important two-dimensional (2D) nanomaterial, with many properties distinct from graphene. In this feature article, these unique properties and associated applications often not possible from graphene are outlined. The article starts with characterization and identification of atomically thin BN. It is followed by demonstrating their strong oxidation resistance at high temperatures and applications in protecting metals from oxidation and corrosion. As flat insulators, BN nanosheets are ideal dielectric substrates for surface enhanced Raman spectroscopy (SERS) and electronic devices based on 2D heterostructures. The light emission of BN nanosheets in the deep ultraviolet (DUV) and ultraviolet (UV) regions are also included for its scientific and technological importance. The last part is dedicated to synthesis, characterization, and optical properties of BN nanoribbons, a special form of nanosheets

“…The stress-strain curves for armchair and zigzag h-BN nanosheets are shown in the inset of GPa -970 GPa from experiment [57], density functional theory [58,59], MD [23,60,8 61] and structural mechanics methods [62,63]. The values are also very close to those of boron nitride nanotubes [63][64][65][66].…”

General rightsThis document is made available in accordance with publisher policies. Please cite only the published version using the reference above. Abstract Kirigami, the ancient Japanese art of cutting and folding paper at the macroscale, has been recently applied to produce nanostructures with unusual deformation mechanisms. In this work we analyse the mechanical properties and deformation mechanisms leading to remarkable stretching and bilinear stiffness in armchair and zigzag hexagonal boron nitride (h-BN) Kirigami nanosheets using classical molecular dynamics simulations. We identify three geometric parameters that govern the mechanics and ductility of Kirigami h-BN. Enhancements in tensile strains up to 3-5 times higher than those of pristine h-BN can be obtained. The variations of stiffness, ultimate strength and strain with the parameters defining the Kirigami defect patterns can be used to tune the mechanical properties of h-BN and other nano 2D structures, potentially expanding their applications in bio-compatible strain-engineered nanodevices and nanoelectronics.

“…However, the half-metallic properties are difficult to be retained at room temperature unless there exists a large half-metallic gap, and the gap is robust to the changes of lattice constants. As a shape memory alloy, the lower stain energy or cohesive energy is required to strain easily, and the relation between stain energy and stain is elaborated by Mirnezhad et al [25][26][27]. Simultaneously, a lower formation energy ensure these alloys can be synthesized in experiment.…”
