[2012.04021] A DFT Study on the Electronic Structure …

2020-12-7 · The structural similarity between hexagonal boron nitride (h-BN) and graphene nanoribbons allows for the formation of heterojunctions with small chain stress. The combination of the insulation nature of the former and the quasi-metallic property of the latter makes this kind of heterostructure particularly interesting for flat optoelectronics. Recently, it was experimentally demonstrated that ...

Heteroepitaxial Growth of Two-Dimensional …

A common method for creating a thin single-crystal layer of a semiconductor for use in an electronic device is heteroepitaxy—growing the layer on the face of a single crystal of a different material that acts as a template for assembly. Liu et al. (p. [163][1]) now describe a similar process in which the edge of a graphene layer that was grown on a copper surface directs the assembly of a ...

Transferable GaN Layers Grown on ZnO-Coated …

Nitride semiconductor materials used in light-emitting diodes and lasers are usually grown on single-crystal sapphire substrates with intermediate buffer layers. Instead, Chung et al. (p. [655][1]) used graphene as a substrate for gallium nitride growth and found that nucleation of the gallium nitride layers was enhanced by first depositing zinc oxide, which grew as vertical nanowalls on the ...
