Towards High-Performance THz Electronics: From Nanoplasma Switches to Electronic Metadevices
In this seminar, we will present innovative device concepts that can outperform the limitations of traditional electronics. The initial segment of the discussion will center on the new concept of electronic metadevices—an analogy to optical metamaterials adapted to the realm of electronics. This concept can enable an ultra-efficient coupling between a metal and a semiconductor, which is a major challenge in nanoelectronics. In the latter part, we will present the concept of nanoplasma switches, an innovative integrated device that can outstrip the constraints of semiconductor devices at high frequencies above 100 GHz. This device operates by inducing plasma formation within a nano-gap, serving as an ultrafast switch with a switching speed exceeding 10 V/ps, a significant improvement over solid-state technology. Electronic metadevices and nanoplasma switches find practical applications in terahertz generation and modulation, leading to new possibilities for the future of ultrafast electronics.
