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.
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关联电子输运。我们认为，在一个特征温度以下，库仑相互作用的长程性质对于确定电导峰的最大电导G(max)的温度依赖性至关重要。关联的顺序隧穿主导输运，产生幂律G(max)∝T(α(end-end)-1)，这是两个卢廷格液体端部之间隧穿的典型特征。我们的预测与最近的测量结果一致。
