A three terminal ring interferometer logic gate

Yi, Juyeon ; Cuniberti, Gianaurelio


We propose a carbon-based logic gate where AND, OR, and XOR logic operations are available. It consists in a carbon nanotube (CNT) ring coupled to three external CNT-leads, two of them used as input channels, and the third as the output one. It is revealed that the total transmission for two inputs displays characteristic interference effects. The constructive interference leading to total ...
