2025年3月19日 · The stacking sequence of two-dimensional hexagonal boron nitride (hBN) is a critical factor that determines its polytypes and its distinct physical properties. Although most hBN layers adopt the ...

2025年3月19日 · A fold in the top hBN layer in TR1 (indicated by a red arrowhead in the top micrograph to the right of c) acts as an efficient scatterer of the HPhP modes of the heterostructure (the ...

2024年10月4日 · Hexagonal boron nitride (hBN), as one of the few two-dimensional insulators, holds strategic importance for advancing post-silicon electronic devices and circuits. Achieving...

2021年9月1日 · In this review, we systematically summarize recent advanced strategies towards the controllable synthesis of 2D hBN using chemical vapor deposition, towards a full control of the domain size, orientation, morphology, layer number, and stacking order, etc.

2022年10月10日 · Folded regions are commonly encountered in a number of hexagonal boron nitride (h-BN)-based bulk and nanostructured materials. Two types of structural modifications occur in folded h-BN layers: local curvature at the folded edges and interlayer shear of the layers which changes the stacking of the overlapping flat regions.

2025年3月21日 · As hBN is a 2D material, its single-layer sheet of atoms can sustain unusually high lattice strain of up to 5%, similar to graphite and other TMDs. ... Bulk hBN crystals synthesized by such a pathway, however, contain ten-fold more defects than the HPHT method. The APHT approach involves the mixing of boron and nitrogen into a molten solvent ...

Hexagonal boron nitride (h-BN) is among the most extensively studied forms of boron nitride, valued for its structural similarity to graphite and excellent thermal and chemical stability.

2024年11月8日 · Moiré superlattice of twisted hexagonal boron nitride (hBN) has emerged as an advanced atomically thin van der Waals interfacial ferroelectricity platform. Nanoscale periodic ferroelectric moiré potentials in twisted hBN allow the hosting of remote Coulomb superlattice potentials to adjacent 2D materials.

2024年12月6日 · Color centers in hexagonal boron nitride (hBN) advantageously combine excellent photophysical properties with the potential for integration in highly compact devices. Progress toward scalable integration necessitates a high quantum efficiency and an efficient photon collection.

2021年10月10日 · Here we demonstrate a simple strategy for controlling SPE creation during the chemical vapor deposition growth of monolayer hBN via regulating surface carbon concentration. By increasing surface carbon concentration during hBN growth, we observe increases in carbon doping levels by 2.4 fold for B-C bonds and 1.6 fold for N-C bonds.
