Evidence is presented of a new cause of Joule heating within a simple electronic device involving a multiwalled carbon nanotube (CNT) mounted on two metal electrodes forming an electrical circuit. This time-resolved, high-resolution in situ observation of metal electrode material melting and its flow driven by the thermomigration and electromigration forces through the CNT channel sheds an additional light on the effects affecting the real electrical performance of the CNT-based devices.
提出了一种新的焦耳加热原因的证据，该原因涉及安装在两个形成电路的金属电极上的多壁碳纳米管（CNT）的简单电子设备。通过 CNT 通道的热迁移和电迁移力驱动的金属电极材料熔化及其流动的这种时间分辨、高分辨率的原位观察，进一步揭示了影响基于 CNT 器件实际电性能的影响。
