Abstract

In this presentation, two critical aspects related to the realization of unconventional electronic devices will be discussed. First, synthetic and fabrication approaches to new organic, inorganic, and hybrid materials are presented. The issues covered are: a. Rational design, realization, and understanding of new electrically-active high-mobility p- and n-type organic semiconductors. b. Development of new solution phase processes for thin-film deposition of inorganic/hybrid semiconductors. c. Development of new solution processable dielectrics exhibiting low leakage and high breakdown fields. The combinations of these materials set allow the fabrication of flexible/transparent electronic circuits and display exhibiting complementary properties compared to current-generation devices. In the second part of this presentation, the importance of organic transistor semiconductor-dielectric interface, playing a critical role in influencing charge transport, is highlighted. In this study, new insights into how the bulk/surface viscoelastic properties of the gate polymeric dielectric modulates the thin-film growth mode, microstructure, and transistor performance of pentacene (a benchmark organic semiconductor) films are discussed.
