Wafer-scale, epitaxial growth of single layer hexagonal boron nitride on Pt(111)

Epitaxial growth of single-domain graphene on hexagonal boron nitride.

Hexagonal boron nitride (h-BN) has recently emerged as an excellent substrate for graphene nanodevices, owing to its atomically flat surface and its potential to engineer graphene's electronic structure. Thus far, graphene/h-BN heterostructures have been obtained only through a transfer process, which introduces structural uncertainties due to the random stacking between graphene and h-BN subst...

Thermal transport across graphene and single layer hexagonal boron nitride

Inter-layer potential for hexagonal boron nitride.

A new interlayer force-field for layered hexagonal boron nitride (h-BN) based structures is presented. The force-field contains three terms representing the interlayer attraction due to dispersive interactions, repulsion due to anisotropic overlaps of electron clouds, and monopolar electrostatic interactions. With appropriate parameterization, the potential is able to simultaneously capture wel...

Hexagonal boron nitride epitaxial layers as neutron detector materials

Micro-strip metal–semiconductor–metal detectors for thermal neutron sensing were fabricated from hexagonal boron nitride (hBN) epilayers synthesized by metal organic chemical vapor deposition. Experimental measurements indicated that the thermal neutron absorption coefficient and length of natural hBN epilayers are about 0.00361 mm 1 and 277 mm, respectively. A continuous irradiation with a the...

Repeated and controlled growth of monolayer, bilayer and few-layer hexagonal boron nitride on Pt foils.

Atomically thin hexagonal boron nitride (h-BN), as a graphene analogue, has attracted increasing interest because of many fascinating properties and a wide range of potential applications. However, it still remains a great challenge to synthesize high-quality h-BN with predetermined number of layers at a low cost. Here we reported the controlled growth of h-BN on polycrystalline Pt foils by low...
