Difference between FET BJT and SET

What is Single Electron Transistor?
These are devices operating at the quantum/nano scale that have switching properties controlled by the removal or injection of a single electron; a device through which only one electron can be transported at a time.

In FET/BJT, based on its input current (BJT) or input voltage (FET), a transistor allows a precise amount of current to flow through it.

In SET, the single electron transistor is a new type of switching device that uses controlled electron tunneling to amplify current or switch the state. The word single electron means that one electron-precision charge transfer through tunneling, which is based on the Coulomb blockade effect.
