Original Abstract

This study deals with the effect of contact and series resistance on the transconductance of OECT. The dependence of transconductance on ratio of Wd/L shows decline from expected linearity. The modeled dependencies presented in this article showed the effect of contact series resistance. The significant decrease of effective voltage is observed mainly for short-channel devices (with high ratio of Wd/L). It was shown that the voltage drop can be described by the division of voltage on resistors in series according to this formula: Rch/(Rch + Rc). The modeled dependencies provide the description for development of OECT with maximum transconductance, and hence sensitivity.
