Regiorandom poly(3-hexylthiophene) on gold: Interfacial electronic structures and photoexcitation kinetics

Interfacial electronic structures (profiles of photoemission intensity vs. photoelectron kinetic energy) and photoexcitation kinetics (profiles of the number of photoelectrons vs. the number of incident photons) of polythiophene on gold are investigated by two-photon photoemission spectroscopy.
