Question

• Single electron transistor operates on:
B.O GMR effect
A.O Coulomb blocked effect
C.O Faraday effect
D.O surface plasmon resonance​

Answer 1

Answer:

Single electron transistor operates on:

A.O Coulomb blocked effect

Answer 2

Single electron transistor operates on (A) Coulomb blocked the effect

Explanation:

• A single-electron transistor (SET) is a switching device that is made up of two tunnel junctions that share a common electrode and uses controlled electron tunnelling to amplify current.
• The technology employed in single-electron transistors is based on quantum tunnelling theory. This action is known as Coulomb blockade, and it is the foundation of SET functioning.
• When the dot grows sufficiently tiny and U begins to exceed thermal energy, even just a single electron cannot tunnel to the dot without the assistance of external gate bias to overcome the dot's Coulomb repulsion.
