The goal of this thesis is to identify and to explore novel ACTFEL phosphor
materials. Several important materials properties relevant to ACTFEL phosphor
development are identified. All of these properties cannot be obtained simultaneously.
Therefore, several key phosphor materials properties are identified as critical to the
development of an ACTFEL...
The accomplishments presented in this thesis are the development of three models
for simulation of space charge generation in the phosphor layer of alternating current
thin-film electroluminescent (ACTFEL) devices and the results from simulation
of these models. First, a single sheet charge model is developed and simulated.
The single sheet...
Hot carrier effects in sub-micron lightly doped drain (LDD) n-channel
MOSFETs under static (DC) stress are studied in order to establish the degradation
mechanisms of such devices. Degradation is monitored as a function of time at various
gate voltages. Under accelerated aging conditions (i.e. large drain voltages) the gate
voltage...
