Carbon nanotube quantum dots on hexagonal boron nitride

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 ...

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...

Quantum Dots and Nanoroads of Graphene Embedded in Hexagonal Boron Nitride

T materials have drawn tremendous attention in the recent past in terms of both interesting fundamental physics and possible applications in future generation devices. Graphene and hexagonal boron nitride (h-BN) are the two most promising candidates for this purpose. 3 Single layers of graphene and h-BN have been fabricated and found to be stable at room temperature. 8 The most significant diff...

TOPICAL REVIEW Graphene on Hexagonal Boron Nitride

The field of graphene research has developed rapidly since its first isolation by mechanical exfoliation in 2004. Due to the relativistic Dirac nature of its charge carriers, graphene is both a promising material for next-generation electronic devices and a convenient low-energy testbed for intrinsically high-energy physical phenomena. Both of these research branches require the facile fabricat...
