Single-electron device using Si nanodot array and multi-input gates

We fabricated a single-electron device (SED) that has many nanodots. Oscillatory characteristics and multi-gate capabilities of SEDs were used to eliminate size fluctuation and achieve a high functionality. We fabricated a Si nanodot array device, which has two input gates and a control gate, and tested its basic operation characteristics experimentally. The device operates as a logic gate with selectable functions when the control gate voltage is changed. We demonstrated that the device exhibits five of six important logic functions
