Transistors

Thin film transistors (TFT), are simple electrical switches used as logic gate operators and are critical to the operation of all electrical circuits. Flexible, bendable, wearable electronics rely on high performing carbon-based transistors. The key to maximizing performance is to develop all elements of the TFT simultaneously as device function relies heavily on interfacial chemistry. Our group therefore has interests in design and evaluation of high-performance carbon-based semiconductors (e.g: organic dyes and single walled carbon nanotubes) and well-defined functional polymer based gating materials. We tune molecular structure to enable favourable self assembly and solid-state arrangement all while optimizing the critical interfaces and morphology to provide next generation electronics.
