Design of Organic Transistor Semiconductors for Logic Elements, Displays, and Sensors

摘要

The early demonstrations of field-effect transistors based on organic semiconductors with high dynamic range utilized single devices incorporating p-channel materials such as thiophene oligomers and pentacene. Through end-group substitution and use of electron-deficient cores, we have built a library of semiconductors with a variety of attributes, including low off-current, n-channel function and chemical sensitivity. Devices containing these materials can be assembled to form complementary circuits, pixel drivers, and chemoselective sensors. Specific properties of these materials have led to a new approach to a polymer-based memory element.
