摘要
传统导体的载流子是电子或空穴,但在具有一维链式结构的聚合物中电子已不是导电的载流子。由液体介质流动形式——"孤波"导出的孤子,以及由孤子和反孤子组成的极化子是导电聚合物除电子外的载流子。极化子和孤子流动所需要的能量比电子流动所需的能量小,所以首先启动的"载流子"不是电子,而是极化子和孤子。
The carriers in metals are electrons or holes, however, not the case in polymer with a chain structure. The soliton from the "solitary wave" and polaron forming from soliton and anti-soliton are another types of carriers for conductive polymers. The energy required for movement of polaron and soliton is smaller than that for electron movement in conductive polymers, therefore the carriers should be polaron and soliton instead of electron.
