Single-Molecule Transistor — •Hongkun Park — Department of Chemistry and Department of Physics, Harvard University, 12 Oxford Street, Cambridge, MA 02138, USA

In this presentation, I will describe the fabrication of three-terminal devices (transistors) incorporating individual molecules and discuss their utility in probing the coupling between the electronic motion and other molecular degrees of freedom. Examples that will be discussed include (1) the excitation of the internal vibrational motion of a molecule induced by single-electron hopping, (2) the Kondo resonance in single-molecule transistor caused by correlated spin screening, (3) the spin-level structures in the Mn12O12 cluster, a prototypical single-molecule magnet, and (4) electroluminescence from individual CdSe nanorods caused by inelastic electron scattering.
