Abstract
This lecture will present a concept based on colloidal metal nanoparticles[1] and nanoclusters[2] on a back-gate device architecture, which leads to well-defined and well-controllable transistor characteristics. The combination of the high-quality chemically synthesis of the materials with scalable surface deposition methods and lithography techniques results in transistors, which show high on/off ratios, reliable transfer characteristics, and good room temperature operation. Furthermore, this concept allows for versatile tuning of the device properties. The results demonstrate the potential of metal particles as solution processed materials for semiconducting devices.
