中文摘要：

结合的聚合物， regioregular poly (3-hexylthiophene )(rr-P3HT ) ，电影被纺纱涂层准备 rr-P3HT 氯仿答案到干净的硅晶片表面上。化学反应和 rr-P3HT 表面上的 Ca 免职的电子结构被同步加速器放射光致核裂变光谱学(SRPES ) 和 X 光检查光致核裂变光谱学(XPS ) 在 situ 调查。在 Ca 免职之上，导致 Ca 的乐队弯曲 rr-P3HT 被观察。另外， Ca 原子优先地与 rr-P3HT 的 S 原子反应。在 Ca 和 C 原子之间的明显的反应都不能被发现。通过原子价乐队系列和 rr-P3HT 截止的第二等的电子的进化的调查在 Ca 免职的进程期间，在 Ca/rr-P3HT 接口的一张精力水平排列图被导出。

英文摘要：

Conjugated polymer, regioregular poly（3-hexylthiophene） （rr-P3HT）, films were prepared by spin-coating the rr-P3HT chloroform solution onto clean silicon wafer surfaces. The chemical re- action and electronic structure of Ca deposition on rr-P3HT surfaces were in situ investigated by synchrotron radiation photoemission spectroscopy （SRPES） and X-ray photoemission spectros- copy （XPS）. Upon Ca deposition, Ca-induced band bending of rr-P3HT is observed. In addition, Ca atoms preferentially react with S atoms of rr-P3HT. No obvious reaction between Ca and C atoms can be found. Through the investigation of the evolution of valence band spectra and secondary electron cut-off of rr-P3HT during the process of Ca deposition, an energy level alignment diagram at the Ca/rr-P3HT interface is derived.
