Transport in Single Atomic Junctions: Strong Correlation and Coulomb Blockade

Abstract

We report here the first observation of the strong correlation and Coulomb blockade effects in a single-atomic junction (single tungsten-atom STM tip). In contrast to previous work the use of an atomic-scale central island makes the change in the electrostatic potential due to the variation of the number of electrons in the island greater than 1eV and thus the electron correlation effect is made more controllable and stable even at room temperature.
