## Description

- description: 'Exciplex-type bilayer organic light-emitting diodes (OLEDs) with ohmic
    contacts exhibited current density-voltage (J-V) characteristics that closely
    matched a simplified analytical model proposed by Nikitenko and Bässler. The analytical
    model is based on the following key assumptions: (i) complete hole-electron recombination
    at the interface between a hole transport layer (HTL) and an electron transport
    layer (ETL), (ii) ohmic contacts at the interfaces between metal electrodes and
    carrier transport layers, and (iii) electric-field-independent carrier mobilities
    in both HTL and ETL. The excellent matching shows that the simplified analytical
    model is sufficient to describe the J-V characteristics of the OLEDs. We also
    demonstrated that if the carrier mobility of one carrier transport layer is known,
    that of the other transport layer can be estimated using the equation derived
    by the simplified analytical model. The simplified analytical model provides a
    useful method to estimate carrier mobilities within carrier transport layers themselves
    in OLEDs. '
