Bilayer composite electrodes for diodes

摘要: An ohmic hole injecting electrode or contact (110, 112) for diode structures is disclosed. It formed of multilayer composite materials and gives superior results in this application. The include a layer high work function inorganic material (112) conductive polyaniline ('PANI') (110). In preferred embodiments (140), the anode has substantial transparency. These can as transparent electrodes light-related diodes such LEDs photovoltaic cells where they exhibit lower turn on voltages higher efficiencies.
