Abstract

The transport properties of electronic devices made from single crystalline molecular semiconductors outperform those composed of thin-films. To further understand the superiority of these extrinsic properties, an understanding of the intrinsic electronic structure and properties is necessary. An investigation of the electronic structure and properties of single crystal α-phase perylene (C20H12), a common donor molecule, is presented using angle-resolved ultraviolet photoemission and x-ray photoelectron spectroscopies. Key aspects of the electronic structure of single crystal α-perylene, critical to charge transport in electronic devices, are determined, including the energetic location of the highest occupied molecular orbital (HOMO), the HOMO bandwidth, and surface work function. In addition, using high resolution XPS, we can distinguish between inequivalent carbon atoms within the perylene crystal and, from the shake-up satellite structure in XPS, gain insight into the intramolecular properties in α- perylene.
