I bought that armchair for $ 48 at a sale .Isn't it a real buy ?

我花了48元買了把椅子，還算便宜吧你懂得福利影院在线观看？

Furthermore, by using Natori theory on the field-effect transistor we study the current-voltage characteristics of deformed carbon nanotube field-effect transistors. For strain deformation, the conductivity of zigzag nanotube presents different characteristics with the remainder of n and 3. For armchair nanotubes, the conductivity does not change with the strain parameter. However, for torsion deformation, the conductivity rapidly increases, specially for the armchair tube. It has many obviously different conductivity behaviors between zigzag tubes and armchair tubes.

We also find that the metal-to-semiconductor transition can be driven by squashing the armchair nanotube along any direction. In case one starts with squashing the tube along a direction that preserves the mirror symmetry, all that needs to be done is to squash the tube to a larger extent, to a point where spontaneous symmetry breaking occurs.

Moreover, since the strain energy of zigzag tubes is larger than that of the armchair tubes with the same semidiameter, the ends of the armchair tubes are easier to be closed than those of the zigzag ones. And the closed structures of the zigzag tubes have a lot of defects, even at 3000 K, there will be few carbon atoms flying away from them.

此外，由于鋸齒型碳管應(yīng)力能比同口徑扶手型碳管的應(yīng)力能大免费在线黄视频播放，使得扶手型碳管比鋸齒型碳管更容易形成端口封閉的結(jié)構(gòu)日韩久久无码AV毛片，且鋸齒型碳管端口的封閉結(jié)構(gòu)出現(xiàn)相對較多的缺陷，甚至在3000K下會有少最碳原子從端口飛離碳管欧美日韩三级在线。

Considering the curvature effect on hooping of nearest-neighboring carbon atoms of armchair carbon nanotubes, the energy band, density of state and velocity of electron of armchair SWNT were analytically derived by using the tight-binding model and Born-Karman boundary condition.

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

So in practically, squashing the armchair carbon nanotube can be used as a general approach to drive the metal-to-semiconductor transition.
