Abstract
En 中文
A physics-based model for electron and hole mobility in an amorphous semiconductor is developed to estimate the mobility limits of an amorphous semiconductor. The model involves band tail state trapping of a diffusive (Brownian motion) mobility and accounts for both drift- and diffusion-induced transport, as normally encountered in the operation of a thin-film transistor. Employing this model leads to a predicted maximum mobility of similar to 70 cm(2)V(-1)s(-1) (similar to 10 cm(2)V(-1)s(-1)) for electrons (holes). (C) 2015 Elsevier B.V. All rights reserved.
