| Abstract: | Leakage current is a main problem for the application of polycrystalline silicon transistor(p-Si TFT),the modeling of leakage current in p-Si TFT is important for designers.Based on thermionic field emission,this paper presents an analytical model by approximating the physical model which shows good agreement with experimental data over a wide range of gate bias and of temperature.The model is suitable for implementation in a circuit simulator. |
