In this paper, the dependence of mobility about temperature in organic thin film transistors (OTFTs) has been discussed. The multiple trap and release (MTR) and variable range hopping (VRH) are introduced according to the temperature. MTR shows a temperature dependent mobility as log()∝T-1, while VRH presents a different temperature characteristic as log(T1.5)∝T-0.25. The conclusion is verified by comparisons with measured data and simulation results.
