Abstract
The electrical behavior of a conducting-polymer/inorganic-nanowire composite is explained with a model in which carrier transport occurs predominantly through a highly conductive volume of polymer that exists at the polymer-nanowire interface. This result highlights the importance of controlling nanoscale interfaces for thermoelectric materials, and provides a general route for improving carrier transport in organic/inorganic composites.
摘要
导电聚合物/无机纳米线复合材料的电行为可以用一个模型来解释，该模型中载流子输运主要通过存在于聚合物-纳米线界面处的聚合物高导体积来实现。这一结果突出了控制热电器件中纳米级界面的重要性，并为提高有机/无机复合材料中载流子输运提供了一种通用途径。
