Short Course - Thin-Film Transistors for Emerging Applications Beyond Silicon
Tuesday 18 February 2025
Cripps Court Conference Centre, Magdalene College, Cambridge, UK
COURSE FOCUS
This course will discuss the fundamentals of oxide and organic thin-film transistors and their operation in the subthreshold regime for low power applications. Oxide and organic semiconductors have a relatively large bandgap, therefore rendering ultra-low electrical off-state current and good optical transparency. The remarkable features of ultra-low off-state currents facilitate deep subthreshold operation, while optical transparency opens up possibilities for multi-modal sensing/modulation in bioelectronics. Subthreshold thin-film transistors have advantages of low power and high gain, which are important for bioelectronic applications, for example real-time electrophysiologic recording. In addition, this course will introduce the novel application of high-channel-count active-matrix neurostimulation, showcasing the expanding role of thin-film transistors beyond traditional applications in display and biosensing.
