The deformed metal-SWNTs and metal-TCNTs can be transformed to semiconductor or insulator due to deformations resulting to variation of the atomic structure and the nearest-atom transfer integral having relation with the directions.Based on the Boltzmann transport equation and n - electronic energy dispersion relations for individual SWNTs, the theoretical model caculating the current and conductance of the SWNTs is deduced. The low-temperature conductances of undoping or doping SWNTs are studied numerically, the calculated results show that, for the doping SWNTs, the conductance is quantized, i.e.

我們從Boltzmann方程出發(fā)被cao的美女，并結合SWNTs的能量色散關系，導出了計算手性SWNTs電導或電流的理論模型五月丁香花综合网，并分別對非摻雜和摻雜SWNTs的低溫電導或電流進行數(shù)值計算最新3D动漫H福利在线观看，結果表明：對于非摻雜的SWNTs，其電導是量子化的free性国产高清精品HD，即電導隨偏壓或電子輸運能量變化呈躍變的臺階式結構国产在线视频区，這些結構隨管徑增大或溫度升高變得不明顯野外农村妇女一级A片视频；對于摻雜SWNTs久久国产免费一区二区，當偏壓為某些特定值V_i時，傳導電流有躍變天天摸夜夜添添到高潮水汪汪，且傳導電流的大小国产真实盗摄在线观看、躍變周期及躍變幅度等不是完全由摻雜后的電子濃度決定的，而與管半徑R及摻雜后Fermi能級附近的電子態(tài)密度有直接關系久久99精品久久久久久66，隨著溫度的升高和管徑的增大www.xxxxx，躍變結構趨于平滑。

A FDTD program was written and the electromagnetic fields for various polarized incident beams are calculated and the polarization states of the diffractive waves are extracted. The relation between the polarization state of the diffraction wave and the grating balzed angle and polarization angle for the linearly polarized incident wave is analyzed; In the spectral range of 1530 ~ 1570nm, the polarization dispersion is studied for the linearly and circularly polarized incident beam.
