the current through the island can be blocked if it requires too much energy to change the number of electrons on the island. The Coulomb blockade effect makes it possible to tune electron ...

Charge is measured in coulombs (C). Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to large groups of electrons. One coulomb of ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

preventing electrons from crossing from one layer to another while creating strong interactions (Coulomb interactions) between the layers. The paper is published in the journal Nature Communications.

1 One way to address this issue and improve predictions is to introduce a correction term, known as the Hubbard U parameter, which accounts for the on-site Coulomb interactions among electrons in ...

The presence of the electron on the quantum dot increases the electrostatic potential, preventing additional electrons from tunneling onto the dot due to Coulomb blockade. By applying a voltage to the ...
