Functional Quantum Spin-Iontronic Materials

Modern technology has evolved to a stage that careful manipulation of a single spin or charge carrier is no longer a formidable task. Our research focuses on a particular aspect of the electrons - their spin degrees of freedom, and spin information can be stored, transferred, and processed all the way from classical to quantum levels. We can efficiently harvest the mutual interactions between spins and ions in nanoelectronic devices (ie, spin-iontronics) for advanced spin control and monitoring. The freedom to combine complex spin systems, ion systems, topological states, and superconductors grants us the unique advantage in bottom-up materials design and construction, while still keeping mass production and integration in check. Our program has a strong emphasis on the development of novel materials and devices towards more powerful yet more energy efficient information processing units, into an era beyond silicon.
