Influence of nanomechanical properties on single-electron tunneling: A vibrating single-electron transistor

Abstract

We describe single electron tunneling through molecular structures under the\ninfluence of nano-mechanical excitations. We develop a full quantum mechanical\nmodel, which includes charging effects and dissipation, and apply it to the\nvibrating C$_{60}$ single electron transistor experiment by Park {\\em et al.}\n{[Nature {\\bf 407}, 57 (2000)].} We find good agreement and argue vibrations to\nbe essential to molecular electronic systems. We propose a mechanism to realize\nnegative differential conductance using local bosonic excitations.\n
