本工作采用人工方法制备了Sb 2 Te 3/Poly（3，4-ethylenedioxythiophene）/Sb 2 Te 3三明治结构。这导致了电导率的同时增加和热导率的降低，这是通过调整沿着导电性更强的平行路径的电流和在导热性更弱的垂直方向上被阻挡的热流来实现的。热电优值最大提高了116%，在523 K时达到1.3.
In this work, Sb2Te3/Poly(3,4-ethylenedioxythiophene)/Sb2Te3 sandwich structure was artificially fabricated. This leads to a simultaneous increase of electrical conductivity and decrease of thermal conductivity by tailoring electric flow along the more-electrically conductive parallel path and thermal flow blocked across the less-thermally conductive perpendicular direction. The maximum of thermoelectric figure of merit was increased by 116%, reaching 1.3 at 523 K.
