ECE Seminar - Key considerations for obtaining high performance contact-controlled thin-film transistors

Source-gated transistors (SGTs) have a relatively long history of development but only recently have mainstream technologies allowed for their effective implementation at scale. This talk is addressed to those interested in efficient analog and mixed signal design with advanced thin-film transistors. They provide a development progression with a forward look toward SGT application to future edge processing of sensor data, signal conditioning, and current-mode driving. Crucially, the concept can be applied in practically any material system. As such, the talk will present the fundamentals of contact effect engineering and modelling, design rules for successful SGT implementation, specifics of performance optimisation in thin-film silicon, organic, and oxide semiconductors, and structural evolutions for additional functionality. Finally, the next step in the evolution of contact-controlled thin-film transistor, the multimodal transistor (MMT) will be briefly introduced.
