چکیده

Cutting and folding 2D systems is one of the explored paths to tune physical chemical properties in one-atom-thick matter. Contrary graphene, boron nitride (BN) nanoribbons are difficult obtain, folded BN nanoribbon structures have not been reported yet. Here, we show that pressure application multiwalled nanotubes leads different types tube internal organizations including formation folds. The new associated with breaking a number tubes, leading either nonorganized form alveoli or an organized stacking h-BN nanoribbons. Irreversible changes morphology (MWBNNTs) take place from ?7 GPa, morphologically modified tubes could be observed up pressures at least 49 GPa. experimental probes utilized included high-resolution transmission microscopy, electron tomography, Raman spectroscopy. Atomistic modeling shows pinch along favor pressure-induced bond-breaking hybridization confirm structure. Both experiments polygonization prominent characteristic MWBNNTs even ambient pressure. Overall, evolution strongly differs their carbon analogues. high mechanical stability geometry interest for composite-based structural materials. On other side, availability opens prospects produce physically properties.

Boron Nitride Nanotubes for Spintronics

With the end of Moore's law in sight, researchers are in search of an alternative approach to manipulate information. Spintronics or spin-based electronics, which uses the spin state of electrons to store, process and communicate information, offers exciting opportunities to sustain the current growth in the information industry. For example, the discovery of the giant magneto resistance (GMR) ...

Longitudinal 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...

Growing Carbon Nanotubes within Boron Nitride Nanotubes

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...

Symmetry breaking in boron nitride nanotubes.

We have imaged boron nitride nanotubes with atomic scale resolution using scanning tunneling microscopy. While some nanotubes show the expected triangular lattice pattern, the majority of the nanotubes show unusual stripe patterns which break the underlying symmetry of the boron nitride lattice. We identify the origin of the symmetry breaking and demonstrate that conventional STM imaging analys...
