  • Diamond-like carbon films for electroluminescent applications

    Creator:
    Kim, Seung-bae
    Abstract:
    White electroluminescence (EL) was observed for the first time from diamond-like carbon (DLC) films at room temperature. Electroluminescence was observed by the application of ac voltages in excess of 200 V to a metal-insulator- semiconductor (i.e. DLC)-insulator-metal (MISIM) device structure. For EL applications, three types of the DLC films were...

  • Instabilities in InP MIS capacitors

    Creator:
    Juang, Min Tzuan
    Abstract:
    The drain current of InP MISPETs is often observed to decrease as a function of time after the application of a positive gate bias which involves an accumulation of electrons in the channel. Various models have been proposed for this drain current drift (DCD) phenomenon. In this thesis, variable-temperature bias-stress...

  • Surface recombination velocity and bulk lifetime in GaAs and InP

    Creator:
    Rastegar, Bahador
    Abstract:
    An analytical expression is derived which allows the bulk minority carrier recombination lifetime, t, and the surface recombination velocity, S, to be extracted from a single noncontact photoconductivity decay (PCD) measurement. This analytical expression is rather complex, but can be reduced to a first order approximation. The first order approximation...

  • Improved stability in ACTFEL devices

    Creator:
    Khormaei, Iranpour
    Abstract:
    The stability of ZnS:Mn AC thin film Electroluminescence (ACEFEL) devices as demonstrated by the brightness-voltage (BV) characteristics is discussed. Two procedures for improvement of the stability are demonstrated. The first method is the addition of a CaS buffer layer to one or both interfaces of the ZnS active phosphor layer....
