Keywords:single electronic device, quadruple-dot single electronic device, pump operation

The common-gate quadruple-dot single electronic device can be pumped by asymmetricalizing the four gate capacitances. Report on what gate capacitance ratio allows pump operation in a specific electron configuration, and at what gate capacitance ratio the maximum bias voltage (critical voltage) at which pump operation occurs takes the maximum value. do. Last time, the survey was conducted by changing the ratio of the outer gate capacitance, but this time, the survey was conducted by changing the ratio of the inner gate capacitance to obtain a higher critical voltage value.
