Current without bias and diode effect in shuttling transport of nanoshafts
arXiv:0804.4392 · doi:10.1088/1367-2630/10/10/103014
Abstract
A row of parallely ordered and coupled molecular nanoshafts is shown to develop a shuttling transport of charges at finite temperature. The appearance of a cu rrent without applying an external bias voltage is reported as well as a natura l diode effect allowing unidirectional charge transport along one field directi on while blocking the opposite direction. The zero-bias voltage current appears above a threshold of initial thermal and/or dislocation energy.
