Abstract
The ionization potential and work function of plasma-polymerized zcrylonitrile thin films have been measured using a low energy electron gun in an ultrahigh vacuum system. The optical absorption and electrical resistivity were also measured as a function of pyrolization temperature and doping. A change in ionization potential, work function, electron affinity and band gap was observed. This is discussed in the light of the structural modification owing to pyrolization and doping. The work function of indium tin oxide was also measured and its use in photovoltaic devices is illustrated.
