Second, the island can also vibrate between the gate electrode and the back-gate electrode, and semi-classical model of two-dimensional vibrating EMSET is proposed;
It is proved that the tilted axis cranking (TAC) model is equivalence to the particle rotor model (PRM) under the semiclassical and mean field approximations.
