Corrosion resistance of monolayer hexagonal boron nitride on copper
Hexagonal boron nitride (hBN) is a layered material with high thermal and chemical stability ideal for ultrathin corrosion resistant coatings. Here, we report the corrosion resistance of Cu with hBN grown by chemical vapor deposition (CVD). Cyclic voltammetry measurements reveal that hBN layers inhibit Cu corrosion and oxygen reduction. We find that CVD grown hBN reduces the Cu corrosion rate b...
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 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...
متن کاملChemical and Bandgap Engineering in Monolayer Hexagonal Boron Nitride
Monolayer hexagonal boron nitride (h-BN) possesses a wide bandgap of ~6 eV. Trimming down the bandgap is technically attractive, yet poses remarkable challenges in chemistry. One strategy is to topological reform the h-BN's hexagonal structure, which involves defects or grain boundaries (GBs) engineering in the basal plane. The other way is to invite foreign atoms, such as carbon, to forge biza...
متن کاملBoron nitride on Cu(111): an electronically corrugated monolayer.
Ultrathin films of boron nitride (BN) have recently attracted considerable interest given their successful incorporation in graphene nanodevices and their use as spacer layers to electronically decouple and order functional adsorbates. Here, we introduce a BN monolayer grown by chemical vapor deposition of borazine on a single crystal Cu support, representing a model system for an electronicall...
