Hexagonal Boron Nitride As an Ideal Substrate for Carbon Nanotube Photonics

Is hexagonal boron nitride always good as a substrate for carbon nanotube-based devices?

Hexagonal boron nitride sheets have been noted especially for their enhanced properties as substrates for sp(2) carbon-based nanodevices. To evaluate whether such enhanced properties would be retained under various realistic conditions, we investigate the structural and electronic properties of semiconducting carbon nanotubes on perfect and defective hexagonal boron nitride sheets under an exte...

Semiconducting hexagonal boron nitride for deep ultraviolet photonics

Hexagonal boron nitride (hBN) has been recognized as an important material for various device applications and as a template for graphene electronics. Low-dimensional hBN is expected to possess rich physical properties, similar to graphene. The synthesis of wafer-scale semiconducting hBN epitaxial layers with high crystalline quality and electrical conductivity control is highly desirable. We r...

Boron-nitride nanotube triggered self-assembly of hexagonal boron-nitride nanostructure.

Molecular mechanics results show that a hexagonal boron nitride (h-BN) membrane can spontaneously assemble on the single-walled boron nitride nanotube (BNNT) in a scroll or helical manner, showing an interesting dependence on h-BN width. The size of BNNTs should meet the required conditions to guarantee self-assembly. Further analyses of energy components and structural geometry show that this ...

Boron Nitride Nanotube Peapods

We demonstrate that boron nitride (BN) nanotubes can be filled "peapod" fashion with C60 molecules. Filling small-diameter BN nanotubes results in a linear chain of C60 molecules in the interior, while filling large diameter BN nanotubes leads to nanorods of crystalline C60 in the interior. Electron beam damage can be used to fuse the encapsulated C60 molecules into carbon nanotubes, leading to...
