Abstract
Based on the double exponential distributions of trap states in the channel of the hydrogenated amorphous silicon thin film transistor (a-Si:H TFT), a new extraction method of the threshold voltage for a-Si:H TFTs has been developed. By taking advantage of the conductivity, the expression of the drain current corresponding to the threshold voltage is obtained. The inclusion of the temperature effect in our model makes accurate the extraction under different temperatures, and results fit well with the experimental data.
