Surface and Interface Analysis of PTCDA/ITO Using X-Ray Photoelectron Spectroscopy （XPS）OU Gu-ping, SONG Zhen , GUI Wen ming , ZHANG Fu-jia1.

School of Basic Courses, Beijing Institute of Machinery, Beijing 100085, ChinaAbstract:Xray photoelectron spectroscopy （XPS） of surface and interface of PTCDA/ITO in PTCDA/p-Si organic-onqnorganic photoelectric detector was investigated. From Cls fine spectrum we found that the binding energy of C atoms in perylene rings was 284.6 eV; and the binding energy of C atoms in acid radical was 288.7 eV; moreover, some C atoms were oxidized by O atoms from ITO. The binding energy of O atoms in C=O bonds and C-O-C bonds was 531.5 and 533.4 eV, respectively. At the interface, the peak of high binding energy in C1s spectrum disappeared, and the main peak shifted toward lower binding energy.[著者文摘]
