Size-Dependent Transport and Thermoelectric Properties of Individual Polycrystalline Bismuth Nanowires
Nanofabrication methods and a device architecture are combined to allow for four‐point electric, thermoelectric, and electric field‐effect measurements on individual Bi nanowires. The figure shows a false‐color SEM image of a typical device used in this study, with the 11 Bi nanowires shown as a red...

Summary: | Nanofabrication methods and a device architecture are combined to allow for four‐point electric, thermoelectric, and electric field‐effect measurements on individual Bi nanowires. The figure shows a false‐color SEM image of a typical device used in this study, with the 11 Bi nanowires shown as a red → white gradient. The temperature dependence of the various transport properties as a function of nanowire width is investigated and discussed. |
