Abstract :
Automatic phase control of the Coulomb-blockade (CB) oscillation of a single-electron transistor (SET) is proposed and experimentally demonstrated. Charges in the memory node (MN) capacitively coupled to the SET control the phase of the CB oscillation. The output signal of the SET can controls chares in the MN. This feedback mechanism automatically adjusts the amount of charges, so that the output signal is leveled with a requested one for arbitrary input signal of the SET. The electrical phase control realizes the demonstration of a multifunctional Boolean logic.
