Crystallographic and electronic structure of self-assembled DIP monolayers on Au(111) substrates

We report a comprehensive study of the self-assembly of a diindenoperylene (DIP) monolayer on Au(111) single crystals exploiting different electron probes ranging from STM and LEED to photoelectron spectroscopy and NEXAFS. By this multitechnique approach, we obtain a full picture of the crystallographic and electronic structure of the DIP layer as well as an insight into the assembly process and the role of the DIP-Au interactions. We contrast these experimental findings with theoretical calculations.
