Charge transport and device physics of high mobility organic field-effect transistors


Over recent years there has been tremendous progress in developing low-temperature, solution-processible organic semiconductors that provide high charge carrier mobilities for both n-type and p-type device operation, good operational stability and other functionalities such as efficient electroluminescene, sensing or memory functions for a variety of applications. We are interested in understanding the charge transport and device physics of these materials and the relationship between molecular structure, microstructure and charge diffusion. In this talk we will review the current status of their technological applications, discuss state-of-the-art in device performance and discuss the physical processes that currently limit their performance and operational reliability and how these limitations may be overcome.
