Abstract

The inherent electronic mismatch between molecules and metals is a general limitation for efficient electron transport in molecule-based electronics, including organic light emitting diodes, nanoscale organic spin-valves, and single-molecule transistors.

In this talk, I will review our recent progress in revealing an upper limit for conductance across metal-single molecule interfaces [1], as well as extreme spin filtering and unusual magneto-transport effects in metal-oxide junctions [2] and half-metallic molecular junctions. These findings can be used to derive general principles for efficient charge and spin transport manipulations at the atomic scale [1-4].
