Abstract

In this project we will study the fabrication of organic and inorganic thin-film transistors (TFT) for the development of flexible inverter circuits. Flexible, lightweight and eventually transparent circuits are some of the main trends on organic electronic devices. The simplest and one of the most important circuits is the inverter which is the building block for digital electronics. Thus, the main purpose of this project is to fabricate and characterize organic p-type semiconducting devices and n-type inorganic transistors for the production of flexible hybrid complementary inverter circuits (CIC-Hi). According to the literature CIC-Hi are the most promising circuits due to their good stability, reproducibility and simple architecture and operation. Here, we aim the use of 6,13-Bis(triisopropylsi¬lylethynyl)pentaceno, named TIPS-pentacene and poly(3-hexylthiophene) (P3HT) for the production of organic p-type TFT and zinc oxide-based materials for the fabrication of n-type inorganic ones. The development of flexible CIC-Hi requires the use of printing techniques (e.g. inkjet, screen printing and spraying) in which the above mentioned materials are compatible with. Thus, we propose the production and study of TFTs containing the active layer deposited by printing techniques. These devices will be fabricated using anodic aluminum oxide as the dielectric layer. The device operation will be evaluated in terms of the TFT environmental stability, bias stress and the influence of different surface treatments. Finally, we aim to contribute to development of printed, flexible and transparent organic electronics. (AU)
