The continuing scaling down of complementary metal oxide semiconductor (CMOS) has led researchers to build new devices with nano dimensions. whose behavior will be interpreted based on quantum mechanics. Single-electron devices (SEDs) are promising candidates for future VLSI applications. due to their ultra small dimensions and lower power consumption. https://www.ealisboa.com/top-sale-AR-10-Vert-Monoband-Indep-10m-2-Ringo-quick-deal/
