本文报道了多壁碳纳米管（MWNTs）与正常金属之间形成的单隧道结的隧道光谱测量。MWNTs中的固有库仑相互作用产生了强的零偏抑制，可以用环境量子涨落理论进行数值拟合。在低温下发现了零偏附近的不对称电导异常，并将其解释为强隧穿区中的法诺共振。
Tunneling spectroscopy measurements of single tunnel junctions formed between multiwalled carbon nanotubes (MWNTs) and a normal metal are reported. Intrinsic Coulomb interactions in the MWNTs give rise to a strong zero-bias suppression of a tunneling density of states that can be fitted numerically to the environmental quantum-fluctuation theory. An asymmetric conductance anomaly near zero bias is found at low temperatures and interpreted as Fano resonance in the strong tunneling regime.
