22_19b/2010Quantum Dot Transistors: 1-Nanometer-Sized Active-Channel Molecular Quantum-Dot Transistor (Adv. Mater. 19/2010)

The properties of a molecular quantum dot system using a novel structure of vertical molecular transistor are reported on p. 2182 by Shachar Richter and co-workers. This C60-based device can be operated in two new modes: voltage-controlled switching and gate-controlled hysteresis. A polaron-based model is used to explain the operation of the transistor and to introduce some general rules for the construction of polaronic molecular transistors.
