We report the observation of alternating current-to-direct current half-wave conversion in the range
of 1­1000 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. © 2010 American Institute of Physics. doi:10.1063/1.3429587
