使用多探针技术在低温下研究单个多壁碳纳米管的低温传输特性。电极和管之间准备低欧姆接触以防止接触的影响。使用二探针和四探针技术进行的测量显示库仑振荡的周期几乎相同，这表明隧道势垒位于每对电极之间的管内。实验和理论模拟表明，局部势垒的存在导致了弱耦合岛链的形成以及观察到的库仑封锁特征。
The low-temperature transport properties of individual multiwalled carbon nanotubes are investigated at low temperatures using the multiple-probe technique. A low-ohmic contact between an electrode and a tube is prepared to prevent the influence of contact. Measurements using two- and four-probe techniques show Coulomb oscillations with nearly the same periods, indicating that the tunneling barriers are inside the tubes between each pair of electrodes. The experiment and the theoretical simulation suggest the existence of local barriers being responsible for the formation of a chain of weakly coupled islands and for the observed Coulomb blockade characteristics.
