在紧束缚模型下计算了含散射体的碳纳米管的透射和反射系数。在k · p方案中得到的结果被证明是基本上有效的，包括完全没有背散射的范围大于晶格常数的散射体，除非势的强度变得与带宽相当。当势强与带宽相当时，背散射出现共振增强，结果与k · p方案完全不同。
The transmission and reflection coefficients of a carbon nanotube with a scatterer are calculated in a tight-binding model. The result obtained in a k · p scheme is shown to be essentially valid, including the complete absence of back scattering for scatterers with range larger than the lattice constant, unless the strength of the potential becomes comparable to the band width. When the potential strength is comparable to the band width, a resonant enhancement of back scattering appears and the result becomes completely different from that in the k · p scheme.
