Nested boron nitride and carbon-boron nitride nanocones
In this letter we extend previously established results for nested carbon nanocones to both nested boron nitride and carbon-boron nitride nanocones. Based purely on mechanical principles and classical mathematical modelling techniques, we determine the energetically favourable structures for nested boron nitride and carbon-boron nitride nanocones. While only three apex angles for boron nitride ...
متن کاملSynthesis of aligned symmetrical multifaceted monolayer hexagonal boron nitride single crystals on resolidified copper.
Atomically smooth hexagonal boron nitride (h-BN) films are considered as a nearly ideal dielectric interface for two-dimensional (2D) heterostructure devices. Reported mono- to few-layer 2D h-BN films, however, are mostly small grain-sized, polycrystalline and randomly oriented. Here we report the growth of centimetre-sized atomically thin h-BN films composed of aligned domains on resolidified ...
متن کاملGrowth and Etching of Monolayer Hexagonal Boron Nitride.
The full spectrum from attachment-kinetic-dominated to diffusion-controlled modes is revealed for the cases of monolayer h-BN chemical vapor deposition (CVD) growth and Ar/H2 etching. The sets of grown and etched structures exhibit well-defined shape evolution from Euclidian to fractal geometry. The detailed abnormal processes for merging h-BN flakes into continuous structures or film are first...
متن کاملComputational studies of carbon decorated boron nitride nanocones
Density functional theory ,(DFT) calculations have been performed to investigate the properties ofcarbon decorated (C-decorated) models of boron nitride (BN) nanocones. To this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the C-decorated models. Theresults indicated that dipole moments and energy gaps could reveal the effects of C-decorations onthe pro...
متن کاملHunting for monolayer boron nitride: optical and Raman signatures.
Properties of few-nanometer-thick boron nitride sheets (often referred to as few-layer BN) have been attracting steady interest over the last several years. [ 1 ] Although individual atomic planes of BN were also isolated [ 2 ] and investigated by transmission electron microscopy (TEM) [ 3–5 ] and atomic force microscopy (AFM) [ 6 ] , interest in BN monolayers has been rather limited, especiall...
