| Summary: | 碩士 === 長庚大學 === 光電工程研究所 === 92 === Organic thin film transistors competitive for applications requiring fabricated on large area coverage and flexible electronic , such as commercial flexible poster、recognizing 、system、sensor、E- Paper. We report on the searches of organic thin film transistors fabrication in our thesis. we will excepted useful for developing of organic transistors. Our investigation has two key point mainly:
(1)The paper hopes to use the high electric coefficient materials : Al 2O3 and HfO2 increase accumulated the electric charge to reduce the voltage of operating by meeting our request of having . At first of the experiment made organic transistors, three groups dielectric layer lie between characteristic curves of received and is tend to made at first by unanimous experiments . In the ID-VD figure, we suppose that it is an electrode and the organic materials is schottky contact relations, so we use the Au instead to regard as Source、Drain, the organic is P3HT
To become Ohmic contact ,and reduce the length of road , and gain the IDVD and IDVG . Figure of organic transistor , ITS characteristic curve is similar to theory.
(2)The paper hopes to build inkjet printing electrode .we hopes to manufacture in the low temperate conditions , and to make in the large-area . At first of the experiment made inkjet printing IJAG metal . The inkjet printing IJAG metal experiment to discover Coffee ring behavior. we are succeed improvement Coffee ring behavior and high resistance to use Hydrophilic and Hydrophobic relation .
