Fluoropolymer-Based Polymer Gate Dielectrics for Organic Thin-Film Transistors

Abstract

To enable highdriving speed and to reduce the charging time of gatecapacitors in the device, a high electrical conductance isrequired. The electrical conductance of a TFT is determinedby the product of charge carrier mobility (semiconductorproperty) and charge carrier density in the channel, governedby the capacitance of the gate dielectric. For organic semi-conductors, great improvements have been reported withinthe last ten years, with carrier mobilities approaching that ofamorphous silicon.
