摘要
The non-linear length-dependent resistance, R(l), observed in single-wall carbon nanotubes (SNTs) is explained through the recently proposed ionization energy (E-1) based Fermi-Dirac statistics (iFDS). The length here corresponds to the carbon atoms number (N) along the SNT. It is also shown that R-y(l(y))<R-x(l(x)) is associated with E-1(y)<E-1(x), which can be attributed to different conducting properties in their respective y and x directions, or due to chirality.
