The molecular orientation and electronic structure of 3,4,9,10-perylene tetracarboxylic dianhydride grown on Au(111)
苝四甲酸二酐在Au(111)表面的取向生长及电子结构研究

The interface electronic structure, molecular orientation and surface morphology of the organic semiconductor 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) grown on Au (111) surface have been studied by means of X-ray photoelectron spectroscopy (XPS), synchrotron radiation ultraviolet photoelectron spectroscopy (SRUPS), near edge X-ray absorption fine structure spectroscopy (NEXAFS) and atomic force microscopy (AFM). It can be seen from the SRUPS results that the Shockley-type Au (111) surface state...
