Nano-scale interface controls for future plastic transistors

Recent fundamental research on nano-scale interface control for organic thin film transistors is presented. The interfaces between the organic channel and the substrate, and between the organic channel and the metal electrodes have the greatest influence on transistor performance. The interface properties also drastically change the operation-stability of the transistor performance. This paper shows the results of a series of experimental investigations on the interfaces in the pentacene OTFT.
