✦ Synopsis

The interaction between electrons and organized organic thin Ðlms was investigated by measuring the energy distribution of photoelectrons injected from a thin silver Ðlm coated with thin organic layers. Electrons with energy above ¿0.8 eV were transmitted ballistically through an organic layer that contains up to Ðve monolayers, each ¿2 nm thick. Elastic scattering processes contribute signiÐcantly to the electron energy distribution only for thicker layers. The transmission of low-energy electrons is controlled mainly by an electrostatic barrier perpendicular to the surface. A signature of a band structure in the organic layer was observed when the electrons were transmitted through 13 layers.
