我们研究了具有两个分子内隧穿势垒的单壁碳纳米管中的相关电子输运。我们建议，低于一个特征温度的库仑相互作用的长程性质变得至关重要，以确定电导峰的最大G（max）的温度依赖性。相关的顺序隧穿占主导地位的传输产生的幂律G（最大）成比例，变量T（α（端-端）-1），典型的隧道两端之间的两个Luttinger液体。我们的预测与最近的测量结果一致。
We investigate correlated electronic transport in single-walled carbon nanotubes with two intramolecular tunneling barriers. We suggest that below a characteristic temperature the long-range nature of the Coulomb interaction becomes crucial to determine the temperature dependence of the maximum G(max) of the conductance peak. Correlated sequential tunneling dominates transport yielding the power law G(max) proportional, variant T(alpha(end-end)-1), typical for tunneling between the ends of two Luttinger liquids. Our predictions are in agreement with recent measurements.
