Alternating Current-to-Direct Current Power Conversion by Single-Wall Carbon Nanotube Diodes

摘要

We report the observation of alternating current-to-direct current half-wave conversion in the range of 1-1000 Hz by single-wall carbon nanotube diode rectifiers, which show a high degree of rectification ( 105). The nanoscale diode rectifier demonstrates a half-wave power conversion efficiency of 20%, which is comparable to that reported for larger metal oxide semiconductor field effect transistor diode designs.
