SINGLE-ELECTRON PARAMETRON

We have suggested a novel family of wireless single-electron digital d evices, based on the parametric excitation principle. The basic cell i s a short array of small conducting islands separated by tunnel barrie rs with relatively low capacitance and conductance. External rf (clock ) field creates conditions for spontaneous breaking of the charge symm etry of the cell. The symmetry may be broken by the signal field provi ded by the neighboring cell(s). This mode ensures robust operation of the parametron-based logic circuits. Moreover, these devices may be re versible, dissipating energy well below k(B)T ln2 per logic operation.
