Enhancing multi-functional capabilities of boron …

In spite of the outstanding properties of boron nitride nanosheets (BNNSs), their applications may be limited due to counterproductive effect of the unavoidable defects in their structure. As such, tailoring the performance of these 2D nanostructures through defect engineering is of crucial importance. In this regard, we have probed the mechanical and thermal properties of defective BNNSs ...

Boron Nitride - IFM

2020-11-13 · Boron nitride (BN) can form compounds with either sp 3-hybridized or sp 2-hybridized bonds.The most studied sp 3-hybridized phase is cubic (c-BN), but there is also a wurtzite phase (w-BN) that is an analogue to the III−nitrides AlN, GaN, and InN.The sp 2-hybridized BN (sp 2-BN) can crystallize into two different phases: hexagonal (h-BN) and rhombohedral (r-BN).

Morphology and bonding measured from …

2019-1-29 · Bonding in the hexagonal, cubic (zincblende), rhombohedral, and wurtzite phases of boron nitride was characterized using core‐level photoabsorption. In the boron and nitrogen 1s photoabsorption cross section we observed resonances that were unique to each of the phases and that were associated with the sp 2 or sp 3 bonding present. These spectroscopic standards were then used to characterize ...

mp-984: BN (hexagonal, P6_3/mmc, 194) - Materials …

BN is Boron Nitride structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two BN sheets oriented in the (0, 0, 1) direction. B3+ is bonded in a trigonal planar geometry to three equivalent N3- atoms. All B–N bond lengths are 1.45 Å. N3- is bonded in a trigonal planar geometry to three equivalent B3+ atoms.

Electronic structure and bonding in hexagonal boron …

2005-12-9 · The bonding, cohesive, and electronic properties of hexagonal boron nitride were studied using density functional theory calculations. The properties of this system were calculated using three different exchange?correlation functionals (local density approximation and two forms of the generalized gradient approximation) to determine their relative predictive abilities for this system.
