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