In this paper, we have investigated the geometries and electronic structures of B-N co-doped carbon nanotube with inside adsorption of water molecules. The charge distributions, band structures and local density of states are calculated by using the first-principles theory in detail. The results show that the water molecules can adsorb stably on the inside surface of the doped nanotube with slight deformation. The π and π* subbands shift upward depending on the sites of the adoptions. The investigations will be beneficial to the biological application of B-N co-doped nanotube.

We utilize molecular dynamics simulations to study the effect of an electric field on the permeation of water molecules through a defective single-walled carbon nanotube (DSWCNT). Compared with a perfect single-walled carbon nanotube (PSWCNT), the behaviors of water molecules respond more quickly under the same electric field in a DSWCNT. Wet–dry phase transition of water molecules occurs when the electric field reaches 0.32 V/nm, which is much lower than the case of the PSWCNT. Besides, the critical electric field is affected by the number of defects. These results pave a way for designing fast wet–dry transition devices and provide a new insight into water permeation through a defective nanochannel.

Electrical Instability

The electrical instability of single-walled carbon nanotube (SWCNT) network-based thin-film transistors is investigated in atmospheric air and under vacuum. Atomic force microscopy images show that the nanotube bundles form X-type and Y-type nodes in the SWCNT-networkfilm. The Raman spectrum reveals that the structural defects in the SWCNTs are negligible. The fabricated SWCNT-network TFTs operate in a p-channel accumulation mode both in air and under vacuum. In contrast, TFTs exposed to atmospheric air environment exhibit lower drain currents and larger hysteresis compared with the vacuum environment case. An analysis of the time-dependent characteristic degradation of the SWCNT-network TFTs also demonstrates that the initial decay of the drain current in atmospheric air environment is more acute than that under vacuum. These results can be explained in terms of the hole-trapping behavior of the water molecules near the nanotubes or at the SWCNT/dielectric interface as well as the compensation effect of the electrons donated by water molecules with free holes in the SWCNT-networkfilm.
