Root Growth of Carbon and Boron Nitride Nanotubes …

We have synthesized boron nitride nanotubes (BNNTs) in an arc in presence of boron and nitrogen species. We find that BNNTs are often attached to large nanoparticles, suggesting that root-growth is a likely mechanism for their formation.

Phase transformations of carbon and boron nitride at …

2020-11-5 · Carbon with its unique physical and mechanical properties, as well as its structural analogue boron nitride, is of great interest for research. Suffice it to say that carbon is the most refractory and, in the crystal lattice of diamond, the hardest substance in nature.

IET Digital Library: Nested boron nitride and carbon …

In this letter we extend previously established results for nested carbon nanocones to both nested boron nitride and carbon-boron nitride nanocones. Based purely on mechanical principles and classical mathematical modelling techniques, we determine the energetically favourable structures for nested boron nitride and carbon-boron nitride nanocones.

Ultralow-dielectric-constant amorphous boron nitride

Here we report three-nanometre-thick amorphous boron nitride films with ultralow κ values of 1.78 and 1.16 (close to that of air, κ = 1) at operation frequencies of 100 kilohertz and 1 megahertz, respectively. The films are mechanically and electrically robust, with a breakdown strength of 7.3 megavolts per centimetre, which exceeds requirements.
