Abstract

Suspended microdevices are employed to measure the in-plane electrical conductivity, thermal conductivity, and Seebeck coefficient of suspended poly(3,4-ethylenedioxythiophene) (PEDOT) thin films. The measured thermal conductivity is higher than previously reported for PEDOT and generally increases with the electrical conductivity. The increase exceeds that predicted by the Wiedemann-Franz law for metals and can be explained by significant electronic thermal transport in PEDOT.

摘要

悬浮微器件用于测量悬浮聚（3,4-亚乙基二氧噻吩）（PEDOT）薄膜的面内电导率、热导率和塞贝克系数。测量得到的热导率高于之前报道的 PEDOT 值，且通常随电导率的增加而增加。这种增加超过了金属的维德曼-弗朗兹定律的预测，可以用 PEDOT 中显著的电子热输运来解释。
