The energy band structure of the conduction band is one of the most fundamental information for understanding electron transport mechanisms in crystalline materials. We have developed angle-resolved low-energy inverse photoelectron spectroscopy (ARLEIPS) to examine the conduction band structure of organic semiconductors. In this study, we applied ARLEIPS to PBTTT-C14 as a polymer and measured the conduction band structure of a conducting polymer for the first time. In the presentation, we discuss the fabrication of highly oriented thin films suitable for ARLEIPS measurements, the data analysis using second derivatives and the band structure obtained.
