Vibration-assisted electron tunneling in C140 transistors.

چکیده
We measure electron tunneling in transistors made from C(140), a molecule with a mass-spring-mass geometry chosen as a model system to study electron-vibration coupling. We observe vibration-assisted tunneling at an energy corresponding to the stretching mode of C(140). Molecular modeling provides explanations for why this mode couples more strongly to electron tunneling than to the other internal modes of the molecule. We make comparisons between the observed tunneling rates and those expected from the Franck-Condon model.

متن کاملVibrational excitation in single-molecule transistors: deviation from the simple franck-condon prediction.
We investigated the inner-sphere reorganization of ferrocene ((Cp) 2Fe ( n+ )) and tris(2,2'-bipyridine) iron ((bpy) 3Fe ( n+ )) in a single-molecule-transistor geometry. In (Cp) 2Fe ( n+ ) ( n = 0 and 1), almost no vibrations were excited during single-electron transport, whereas in (bpy) 3Fe ( n+ ) ( n = 1, 2, and 3), many distinct vibrations appeared, consistent with its larger reorganizatio...
متن کاملInelastic electron tunneling via molecular vibrations in single-molecule transistors.
In single-molecule transistors, we observe inelastic cotunneling features that correspond energetically to vibrational excitations of the molecule, as determined by Raman and infrared spectroscopy. This is a form of inelastic electron tunneling spectroscopy of single molecules, with the transistor geometry allowing in situ tuning of the electronic states via a gate electrode. The vibrational fe...
متن کاملBallistic (n,0) Carbon Nanotube Field Effect Transistors' I-V Characteristics: A Comparison of n=3a+1 and n=3a+2
Due to emergence of serious obstacles by scaling of the transistors dimensions, it has been obviously proved that silicon technology should be replaced by a new one having a high ability to overcome the barriers of scaling to nanometer regime. Among various candidates, carbon nanotube (CNT) field effect transistors are introduced as the most promising devices for substituting the silicon-based ...
متن کاملSymmetry dependence of vibration-assisted tunneling.
We present spatially resolved vibronic spectroscopy of individual pentacene molecules in a double-barrier tunneling junction. It is observed that even for this effective single-level system the energy dissipation associated with electron attachment varies spatially by more than a factor of 2. This is in contrast to the usual treatment of electron-vibron coupling in the Franck-Condon picture. Ou...
