| Plastic electronics is an emerging technology with the potential to replace traditional silicon electronics. Plastic electronics uses organic materials that are easily deposited using very cost effective techniques such as spin coating, drip coating and ink jet printing. These materials can be deposited on thin, flexible substrates, making this technology very attractive, especially in the display industry.; Organic transistors are the cornerstone of this new plastic electronics technology. Besides the semiconductor material, the gate dielectric material is also very important, since most organic semiconductors have low mobilities. To increase the transconductance, a high dielectric constant material has to be used to counteract the low mobility values. The use of tantalum pentoxide as the gate dielectric was studied in this project. The goal of the research project was to show that tantalum pentoxide would be a good gate dielectric for organic transistors; unfortunately problems with fabrication and the semiconductor material prevented high-quality performance. |
