A Molecular Quantized Charge Pump.
Summary of "A Molecular Quantized Charge Pump."
A novel single electron pump based on individual molecules (a single wall carbon nanotube) is discussed in terms of the hybrid superconducting-normal conducting pumping principle. A concept demonstration device has been built based on a carbon nanotube contacted by Nb-Ti leads. Charge current quantization is achieved through rf modulation of the back gate voltage. The device is able to transfer a given number of electrons per pumping cycle. Single electron pumping is achieved for pumping frequencies up to 80 MHz.

Medical and Biotech [MESH] Definitions
Ions
An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.
Charge Syndrome
Rare disease characterized by COLOBOMA; CHOANAL ATRESIA; and abnormal SEMICIRCULAR CANALS. Mutations in CHD7 protein resulting in disturbed neural crest development are associated with CHARGE Syndrome.
Molecular Epidemiology
The application of molecular biology to the answering of epidemiological questions. The examination of patterns of changes in DNA to implicate particular carcinogens and the use of molecular markers to predict which individuals are at highest risk for a disease are common examples.
Evolution, Molecular
Evolution at the molecular level of DNA sequences and proteins. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Molecular Sequence Annotation
The addition of descriptive information about the function or structure of a molecular sequence to its MOLECULAR SEQUENCE DATA record.
