A new type of Metal Oxide Semiconductor (MOS) transistor that works on the basis of the Quantum Interference Depression (QID) effect is disclosed. QID occurs inside an n-type semiconductor source-drain electrode of special geometry. Due to QID the Fermi level of said semiconductor increases locally inside the source drain electrode, thereby creating a localised potential energy barrier in the path of electrons moving from source to drain regions. The height of the barrier depends on the degree of QID. QID is in turn regulated by the gate voltage via the charge depletion and hence change in effective dimensions of the special geometry of the semiconductor electrode. A gate voltage modulated potential energy barrier and is thus formed whereby current in said MOS transistor is controlled.
