Abstract

We show that electric current can be generated in metallic carbon nanotubes immersed in liquids flowing along them. Molecular layers of the liquid coat the nanotube, slip along its surface, and excite there a phonon wind, which drags free carriers in the tube. The induced electric current should allow building of nanoscale detectors or power cells.

摘要

我们表明，在沉浸于沿其流动的液体中的金属碳纳米管中可以产生电流。液体的分子层包覆纳米管，沿其表面滑动，并在那里激发声子风，声子风会拖动纳米管中的自由载流子。感应电流应有助于构建纳米级探测器或能量电池。
