Abstract

We have developed a photoelectron yield Spectroscopy (PYS) apparatus which enables us to measure work functions of metal electrodes and ionization potentials (IPs) of organic electronic materials in both vacuum and atmospheric conditions. By using UV spectral light source purged by nitrogen gas and sub-pico ammeter for detecting photoelectrons, our apparatus can measure a wide range of IPs of organic materials including not only hole transporting materials but also electron transporting materials. We will report on the details of the apparatus as well as some examples of the measurements. In addition, the application of this technique to characterize the electronic structure of organic / metal interfaces will be also reported.
