单个单壁碳纳米管沉积在多个（多达七个）铂纳米电极实现。两个探针和四个探针之间的运输测量相邻的电极对显示类似的，但不相同的单电子库仑充电签名在低温下。观察表明，纳米管可以表现为串联连接的量子线链。我们认为，分离这些岛的局部障碍可能是由于弯曲的管附近的电极的边缘。
Deposition of individual single-wall carbon nanotubes over multiple (up to seven) Pt nanoelectrodes is realized. Two-probe and four-probe transport measurements between adjacent pairs of electrodes show similar but not identical single-electron Coulomb charging signatures at low temperatures. The observations indicate that nanotubes can behave as a chain of quantum wires connected in series. We argue that the local barriers separating these islands may be caused by bending of the tube near the edges of electrodes.
