  • Abstract
    Discusses the extraction of threshold voltage for n and p channel polysilicon thin film transistors. First, the effect of measurement frequency is investigated, both experimentally and via 2D numerical device simulation. The temporal characteristics ofthe boundary traps are shown to cause a significant positive (negative) shift of the gate to channel capacitance curve for n-channel (p-channel) TFTs as a function of frequency.
