| 中文摘要 | We report the current-voltage ( I-V) characteristics and electrical conductivity of individual template-synthesized poly( 3,4-ethylenedioxythiophene) ( PEDOT) nanowires ( 190 +/- 6 nm in diameter and sigma(RT) = 11.2 +/- Omega(-1) cm(-1)) over a wide temperature range from 300 to 10 K. With lowering temperature, the I-V characteristics become nonlinear around 50 K, and a clear Coulomb gap-like structure appears in the differential conductance ( dI/dV) spectra. The temperature dependence of the resistance below 70K follows ln R proportional to T(-1/2), which can be interpreted as Efros-Shklovskii hopping conduction in the presence of a Coulomb gap. In addition, the influences of measurement methods such as the applied bias voltage magnitude, the two-probe and four-probe techniques used in the resistance measurements are also reported and discussed. |
