evidence for graphite-like hexagonal aln nanosheets

Recent progress in polymer dielectrics containing boron

Hexagonal boron nitride nanosheets (BNNSs) are two‐dimensional nanomaterials with graphitic‐like layered nanostructures, high surface areas, and large aspect ratios. Owing to their excellent thermal conductivity, electrical and mechanical strengths, BNNSs are emerging as multifunctional fillers in polymer dielectrics.

Evidence for graphite-like hexagonal AlN nanosheets epitaxially grown on single crystal Ag(111) more by Alessandro Molle and E. Xenogiannopoulou ABSTRACT Ultrathin (sub-monolayer to 12 monolayers) AlN nanosheets are grown epitaxially by plasma assisted molecular beam epitaxy on Ag(111) single crystals.

Ferromagnetism in freestanding MoS 2 nanosheets

2013/3/16MoS 2 nanosheets were prepared through exfoliation of bulk MoS 2 (purchased from the JK Chemical, Beijing, China) with different times. In a typical synthesis progress, 0.5-g MoS 2 powders were sonicated in N,N-dimethylformamide (DMF, 100 mL)

Van der Waals and Graphene

Thus, the transformation from graphite-like (sp 2-hybridization, see Figure 11a) to wurtzite structure of AlN (sp 3-hybridization, Figure 11b) is observed. This transition is similar to the transition metastable graphene-like silicon nitride of the structure (8 8) to stable amorphous phase a-Si 3 N 4 .

Evidence for graphite

Ultrathin (sub-monolayer to 12 monolayers) AlN nanosheets are grown epitaxially by plasma assisted molecular beam epitaxy on Ag(111) single crystals. Electron diffraction and scanning tunneling microscopy provide evidence that AlN on Ag adopts a graphite-like hexagonal structure with a larger lattice constant compared to bulk-like wurtzite AlN.

Introduction 2D materials, or nanosheets, are a class of nanomaterials that draws more and more attention since graphene was discovered. 1 These 2D materials exhibit a sheet‐like structure, hence the name nanosheets, with lateral dimensions of tens to hundreds of nanometers to even micrometers, and thicknesses no more than 5 nm. 2 Owing to the effect of spatial confinement in one dimension

Recently, two-dimensional gallium and aluminum nitrides have triggered a vast interest in their tunable optical and electronic properties. Continuation of this research requires a detailed understanding of their atomic structure. Here, by using first-principles calculations we reported a systematic study of phase stability of 2D-GaN and 2D-AlN. We showed that the films undergo a phase
