Abstract: We implement and demonstrate a scheme that permits to driveelectroluminescence with an extremely low turn-on voltage. The device behaveslike compound semiconductors, in which the electroluminescence turn-on voltageis about the same as the open circuit voltage for the photovoltaic effect.However, the electroluminescence turn-on voltage is about half of the band gapof the emitting material, that cannot be explained using current models ofcharge injection in organic semiconductors. We hereby propose explanationthrough an Auger-type two-step injection mechanism Auger-fountain.
