Single-molecule transistors

Article Abstract:

New nanometer-scale transistors have drawn close to the ultimate in miniaturization in that they consist of only one carbon-based molecule. The laws of quantum mechanics determine the operation of the transistors. Development and operation details are discussed.

Coupled quantum dots as artificial molecules

Article Abstract:

Quantum dots, tiny semiconductor devices consisting of a few enclosed electrons, have shown quantum-mechanical properties due to their small size. Recent experiments show that coupled quantum dots can act like coupled atoms in a molecule.
