我们报道了一种碳纳米管（CNT）环形晶体管的整流特性，这种晶体管由CNT引线连接，其新颖的特性最近已被H。渡边角Manabe，T. Shigematsu和M.清水[Appl. Phys. Lett. 78，2928（2001）]。这封信包含了实验观察所证实的结果。此外，我们报告的额外功能的传输与打破铅反转对称的可能性，这一环设备。线性电导表现出棋盘状的行为，交替出现异常的零线，这在实验中应该是可以直接观察到的。我们也能够区分我们的结果（准维禁闭）从纯拓扑效应（环配置），从而有助于获得丰富的环现象的物理直观的结构特性。
We report results on the rectification properties of a carbon nanotube (CNT) ring transistor, contacted by CNT leads, whose novel features have been recently communicated by H. Watanabe, C. Manabe, T. Shigematsu, and M. Shimizu [Appl. Phys. Lett. 78, 2928 (2001)]. This letter contains results which are validated by the experimental observations. Moreover, we report on additional features of the transmission of this ring device which are associated with the possibility of breaking the lead inversion symmetry. The linear conductance displays a chessboardlike behavior alternated with anomalous zero lines which should be directly observable in experiments. We are also able to discriminate the structural properties showing up in our results (quasione-dimensional confinement) from pure topological effects (ring configuration), thus helping to gain physical intuition on the rich ring phenomenology.
