A Study on Defects in Organic Semiconductors for Field Effect Transistors

Abstract

The understanding and the modeling of mechanisms involved in organic semiconductors are the aims of this Ph.D. thesis. In particular, the document focuses the attention on the role played by organic semiconductor defectson the electrical performance of organic-based field effect transistors. Critical issues are, indeed, the localized states related to the presence of structural defects and chemical impurities. They dominate the charge carrier transport in organic semiconductors and define the quality of interfaces occurring in the transistors... [edited by Author]
