采用悬浮微器件测量悬浮聚（3,4-乙烯二氧噻吩）（PEDOT）薄膜的面内电导率、导热系数和塞贝克系数。测得的热导率比先前报道的PEDOT高，并且通常随着电导率的增加而增加。这一增长超出了Wiedemann-Franz定律对金属的预测，可以用PEDOT中显著的电子热输运来解释。
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.
