The mechanisms of carrier generation and transportation, and interface generation have been investigated in regioregular polyalkylthiophenes (HT-PATs) as the target material. It was revealed that: (1) Al/HT-PAT/Au diode is constituted by Schottky contact at Al/HT-PAT interface and Ohmic contact at HT-PAT/Au. The thickness of depletion layer was estimated to be several ten nanometers. (2) Mobilities of HT-PATs increased with the decrease of alkyl chain length. The maximum mobility was obtained to be 0.01 cm^2V/s in butyl system. (3) Direct measurements of potential distribution revealed that 95% potential drops at Al/HT-PAT6 interface in Al/HT-PAT6/Au cell. HT-PAT6/Au interface also has 100 kΩ as the contact resistance.

研究了以区域规则聚烷基噻吩（HT-PATs）为靶材料的载流子生成、输运和界面生成机理。结果表明：(1)Al/HT-PAT/Au二极管由Al/HT-PAT界面处的肖特基接触和HT-PAT/Au界面处的欧姆接触组成。损耗层的厚度估计为几十纳米。(2) ht - pat的迁移率随烷基链长度的减小而增加。在丁基体系中迁移率最高可达0.01 cm^2V/s。(3)电位分布的直接测量表明，在Al/HT-PAT6/Au电池中，95%的电位下降在Al/HT-PAT6界面。HT-PAT6/Au接口也有100 kΩ作为接触电阻。
