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 ...

is measured in amperes or amps for short (A) time (\(\text{t}\)) is measured in seconds (s) One amp is the current that flows when one coulomb of charge passes a point in a circuit in one second.
