Thin films: Rolling out organic electronics

A new approach which has the potential to exploit composite phase behavior facilitates the manufacture of crystalline films from solution for high-quality devices, is described. As a fundamental building block of electronics, the transistor needs to be capable of operating reliably at a minimum performance level, characterized by the charge-carrier mobility and the ON/OFF ratio. Evaporative deposition of small molecules has led to high-performance devices, but requires detailed control of deposition rates. A full-color, flexible display operating at speeds consistent with video rates and consisting of organic light emitting diodes (OLED) driven by organic field effect transistors (OFET) offers benefits of being fabricated by printing techniques.
