| 摘 要： | 通过分析聚丁二炔（ＰＤＡ＇Ｓ）中的稳态和瞬态光电流衰减的光生载流子迁移率，提出了一个新的光生载流子输运模型．认为光电流衰减的初始快速（ｐｓ级）分量是由于广延带态中的“热”载流子，而较长时间（ｎｓ级）的分量是由于缺陷（如链端等）支配着输运，是其一维特性的结果．

| Abstract: | hrough analyzying photocarrier mobilities in stationary and transient photocurrent decay in polydiacetylene-(bis-p-toluene sulfonate), PDA-TS, a new photocarrier transport model is presented. The fast (picosecond) initial component of photocurrent decay is due to hot carriers in extended band states, and the longertime (nanosecond) component of photocurrent decay is defects (chain end) dominated transport and due to its one-D character. |

| Keywords: | Photo-generating carrier Stationary photocurrent Carrier mobility Carrier transport Photocurrent decay Transient photocurrent |
