Valley Blockade Quantum Switching in Silicon Nanostructures / E. Prati. - In: JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY. - ISSN 1533-4880. - 11:10(2011), pp. 8522-8526. [10.1166/jnn.2011.4957]
Abstract:
In analogy to the Coulomb and the Pauli spin blockade, based on the electrostatic repulsion and the Pauli exclusion principle respectively, the concept of valley blockade in Silicon nanostructures is explored. The valley parity operator is defined. Valley blockade is determined by the parity conservation of valley composition eigenvectors in quantum transport. A Silicon quantum changeover switch based on a triple of donor quantum dots capable to separate electrons having opposite valley parity by virtue of the valley parity conservation is proposed. The quantum changeover switch represents a novel kind of hybrid quantum based classical logic device.
