چکیده
Using the method of molecular dynamics and a 2D chain model, it is shown that thermophoresis carbon nanoparticles (nanoribbons nanotubes) on flat multilayer substrate (on surface hexagonal boron nitride crystal) has high efficiency. Placing nanoparticle involved in heat transfer leads to its movement direction flow. The flow along formation constant forces acting nodes (thermophoresis forces). main effect force exerted edges graphene nanoribbons, exactly where interaction nanoribbon with bending phonons occurs. These have long free path, so effective using can occur at sufficiently large distances. motion under action form particle viscous medium force. Over time, always enter mode speed. velocity stationary almost same for all sizes types nanoparticles, which explained by fact friction source --- thermal vibrations layers. Keywords: nanotubes, substrates, thermophoresis, model substrate.

STM Spectroscopy of ultra-flat graphene on hexagonal boron nitride
Graphene has demonstrated great promise for future electronics technology as well as fundamental physics applications because of its linear energy-momentum dispersion relations which cross at the Dirac point[1, 2]. However, accessing the physics of the low density region at the Dirac point has been difficult because of the presence of disorder which leaves the graphene with local microscopic el...

The controlled synthesis and growth of carbon nanotubes (CNTs) has been a long standing challenge in the fabrication of carbon based materials for electronic applications. Due to the sensitivity to small changes in their structure, the successful integration of CNTs on electronic devices is conditioned to the preservation of the graphitic network of single and multiwalled nanotubes from externa...

Graphene nanoribbons (GNRs) are ultra-narrow strips of graphene that have the potential to be used in high-performance graphene-based semiconductor electronics. However, controlled growth of GNRs on dielectric substrates remains a challenge. Here, we report the successful growth of GNRs directly on hexagonal boron nitride substrates with smooth edges and controllable widths using chemical vapou...
متن کاملLongitudinal splitting of boron nitride nanotubes for the facile synthesis of high quality boron nitride nanoribbons.
Boron nitride nanoribbons (BNNRs), the boron nitride structural equivalent of graphene nanoribbons (GNRs), are predicted to possess unique electronic and magnetic properties. We report the synthesis of BNNRs through the potassium-intercalation-induced longitudinal splitting of boron nitride nanotubes (BNNTs). This facile, scalable synthesis results in narrow (down to 20 nm), few sheet (typicall...
