Comparative Study of Electrical Characteristics of Organic Field Effect Transistor using both PEDOT: PSS and Pentacene as a Organic Material

Abstract

In this paper, the analytical modeling of an Organic Field Effect transistor (OFET) has been carried out  to investigate the electrical characteristics using different organic semiconductor. Two different organic semiconductor material such as Pentacene and poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT:PSS)has been used as an active material in the channel region with channel length 180nm, 220 nm and 260 nm respectively.   From the mathematical modeling the output characteristics curve, Transfer curve and drain current behavior for the different channel length has been studied. The overall comparative analysis of the two different organic materials in the channel shows that Pentacene offers better electrical performance in compare to PEDOT:PSS counterpart.
