Abstract
We have analyzed numerically back gate effects of a-Si TFT under illum ination with a 2-dimensional device simulator. In this simulator, all localized states were taken into account as recombination centers and as charge trapping centers by Shockley-Read-Hall statistics according to the Simmons-Taylor's analysis. The simulation results explain well the enhancement of the TFT OFF current under illumination and the shou lder-like increase of the dark OFF current which were generally observ ed experimentally.
