Water induced bandgap engineering in nanoribbons of hexagonal boron nitride
Chen Chen, Yang Hang, Hui Shan Wang +13
Different from hexagonal boron nitride (hBN) sheets, the bandgap of hBN nanoribbons (BNNRs) can be changed by spatial/electrostatic confinement. It has been predicted that a transv…

Signatures of magnetism in zigzag graphene nanoribbon embedded in h-BN lattice
Chengxin Jiang, Hui Shan Wang, Chen Chen +18
Zigzag edges of graphene have long been predicted to exhibit magnetic electronic state near the Fermi level, which can cause spin-related phenomena and offer unique potentials for…
