Abstract
The gradual channel approximation is widely used for organic field-effect transistors with an assumption of linear potential profile across the channel. However, this is in contradiction with reported potential profiles. Here, we discuss linear and nonlinear potential profiles in the meaning of the space-charge field generated by injected carriers. The influence on current-voltage relation used for mobility evaluation in linear and saturated regions is proposed as well as transition between these states. In addition, the effect of the space-charge on the potential drop and field around the drain electrode in the saturation region is discussed.
