Topic：Paramagnetic Molecule-based Spin Valves: New Paradigms in Molecular Spintronics
Time：Jan 8, 10:00-11:00
Location：Room 1A-200, SIST Building
Speaker：Prof. Frank Tsui
The emerging field of spintronics envisions devices based on spin-polarized carriers and their transport in solids for developing the next generation of ultra-miniature, energy efficient computational and information technologies. Recently, paramagnetic radicals/molecules based spin valve devices have been discovered. Here, we describe several experiments employing these concepts, including the use of a cobalt dioxolene complex, whose spin states are switchable by various external stimuli, including temperature, light exposure, and electric and magnetic fields.
Prof. Frank Tsui got his BS in Engineering Physics from the University of California at Berkeley, Master in Applied and Engineering Physics from Cornell University, and PhD in Physics from the University of Illinois at Urbana-Champaign. He is now a full professor at the department of Physics and Astronomy at the University of North Carolina at Chapel Hill. His current research interests include: Novel synthesis and characterization of self-assembled nanostructures, and metastable materials; Magnetic thin films and heterostructures: combinatorial MBE synthesis, structural, magnetic and transport effects, electronic structures, and device concepts; and Phenomena in systems of reduced dimensions.
