Field emission properties of patterned boron nanocones.
Large area patterned boron nanocones with low turn-on electric field of 2.8 V microm(-1) and low threshold electric field of 3.8 V microm(-1) were synthesized by a pre-manipulation to pattern the catalyst with a grid template as mask. The good field emission performance of patterned boron nanocones arise from the decreased screening effect and a favorable orientation of the nanocones. These res...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولField emission and strain engineering of electronic properties in boron nitride nanotubes.
The electrical properties of boron nitride (BN) nanostructures, particularly BN nanotubes (NTs), have been studied less in comparison to the counterpart carbon nanotubes. The present work investigates the field emission (FE) behavior of BNNTs under multiple cycles of FE experiments and demonstrates a strain-engineering pathway to tune the electronic properties of BNNTs. The electrical probing o...
متن کاملField emission and current-voltage properties of boron nitride nanotubes
We have measured electrical transport properties of boron nitride nanotubes using an in situ manipulation stage inside a transmission electron microscope. Stable currents were measured in a field emission geometry, but in contact the nanotubes are insulating at low bias. At high bias, the nanotubes show stable, reversible breakdown current. q 2003 Published by Elsevier Ltd.
متن کاملQuantum mechanical study of electronic and structural properties of methyl benzoate in interaction with boron nitride (BN) nanotube
To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...
