Design, simulation and performance evaluation of a single-electron 2-4 decoder

In this paper, we present a single-electron 2-4 decoder built using single-electron devices. The circuit is designed using a proper tool based on a Monte Carlo technique. First a single-electron AND gate is studied and then the 2-D decoder circuit is designed and studied. The results proved that the circuit was a 2-4 decoder, while the behaviour of the free energy of the system (which was calculated to be 4.90×10−1 eV) and the stability diagram verified the correct functioning of the circuit.
