Surface Potential Based Model for Amorphous IGZO Thin Film Transistors
An analytical dc model is presented for amorphous In-Ga-Zn-Oxide (a-IGZO) thin Film transistors on the basis of surface potential calculation by Lambert W equation, assuming an exponential trap states density within the bandgap. Charge sheet approximation is utilized to derive the trapped and free charges. The model results are compared with experimental data and a good agreement is achieved.
