  • Abstract
    The field effect mobility in an oxide thin film transistor (TFT) is studied theoretically. Based on a multiple-trapping and release model, a unified expression for field effect mobility is formulated for oxide TFTs. This model can well explain the temperature and gate voltage dependent mobility observed in oxide TFT. The effect of localized states distribution on the field effect mobility is also demonstrated.
