Highly functional three-terminal nanodot array device with almost independent input gates

Nanodot array devices work as a function-selectable logic device. This functionality can be achieved by the multi-input gates coupled to the same nanodots. In this report, we show the complicate functionality by the use of a nanodot array with almost independent two input gates, which is not predicted from the orthodox theory. The phenomena may be attributed to illegal current peak modulation caused by a very small electric field applied through the nanodot array in the few electron regime.
