Electronic sensitivity of carbon nanotubes to internal water wetting.
We have constructed devices in which the interior of a single-walled carbon nanotube (SWCNT) field-effect transistor acts as a nanofluidic channel that connects two fluid reservoirs, permitting measurement of the electronic properties of the SWCNT as it is wetted by an analyte. Wetting of the inside of the SWCNT by water turns the transistor on, while wetting of the outside has little effect. T...
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 اول1999: Nanocapillarity: Wetting of Carbon Nanotubes
It is well documented in the modem literature that the conventional laws of capillarity such as Laplace, Kelvin, and Young-Dupre equations are not adequate when applied to fluids confined by particulate and porous materials. Specifics of interactions of fluids with solid surfaces at the nanoscale are of special engineering importance in view of recent discovery of carbon nanotubes and rapidly g...
متن کاملStatic and dynamic wetting measurements of single carbon nanotubes.
Individual carbon nanotubes were immersed and removed from various organic liquids using atomic force microscopy. The carbon nanotube-liquid interactions could be monitored in situ, and accurate measurements of the contact angle between liquids and the nanotube surface were made. These wetting data were used to produce Owens and Wendt plots giving the dispersive and polar components of the nano...
متن کاملInteractions between Carbon Nanotubes and Liquids: Imbibition and Wetting
We report on our progress to extend the current experimental measurements of interactions between fluid and materials to times and length scales characteristic of nanomaterials. The rapid imbibition of decane and nonpolar fluids by carbon nanotubes is investigated to confirm recent theoretical results obtained using MD simulations. The wetting dynamics of carbon nanotubes and larger carbon fibr...
