Web3 giu 2024 · Experiments on the hydrostatic compression of h-BN made it possible to understand the different nature of intralayer and interlayer interactions in h-BN and to control the bandgap [251].
WebIt is well established that h-BN is a direct bandgap semiconductor while c-BN is an indirect bandgap material. In the case of h-BN the value of p is 1/2 in the (αhν) p vs. E g (Tauc) plot while p is equal to 2 for c-BN in the same plot due to the band to band transition. Therefore, sample A, which is predominantly composed of h-BN, is fitted ... WebIn case of symmetric heterostructures, the h-BN encapsulation retain the atomic structures and the electronic properties of graphene, particularly maintaining its zero bandgap. In case of asymmetric structures, the effect of the h-BN substrate is to provide an effective staggered potential which could be compensated by an external electric field.
