报告内容:

  This talk presents one-dimensional organometallic sandwich molecular wires (SMWs) as a versatile platform for molecular spintronics. These hybrid structures exhibit half-metallicity, perfect spin filtering, and stimuli-responsive conductance switching. We elucidate the underlying mechanisms using crystal field theory and spin-dependent transport calculations, and demonstrate reversible switching between semiconducting, metallic, and half-metallic states via external stimuli. Finally, we discuss surface assembly strategies using heteroatomic ligands for seamless integration with semiconductor platforms, positioning SMWs as promising candidates for next-generation spintronic devices.
