Abstract: A novel field emission Carbon Nanotube (CNT) - based controlled switch is introduced in the second part of the article. For the architecture effectuation of the new CNT field emission – based switching device, four field emission tubes having single CNT as emitters were previously tested and compared to a tungsten-tip tube, and the corresponding Fowler-Nordheim analysis was performed. Measurements conducted with the CNT suggested that mixer current could be 30 times greater if either SWCNT or MWCNT were used in place of metal emitters, increasing the microwave output power by 30 dB. Laser radiation was utilized to increase field emission current from a cathode with a dense field of CNT by a factor of 18. The extension of the new device from the two-valued to the general m-valued case is introduced, and the implementation of many-valued Galois circuits and systems is also shown.
