  • Abstract
    The current-voltage characteristics of an Alq3-based hole-only device (ITO/Alq3/Au) are measured against temperature. As the hole current is space-charge limited, the hole mobility μp against electric field and temperature was measured directly. The hole mobility exhibits a field dependence as observed for other disordered materials such as amorphous glasses.
