Single-electron logic device based on the binary decision diagram

The unit device consists of four tunnel junctions and operates as a two-way switch for single-electron transport. Any combinational logic can be implemented by connecting identical unit devices into a cascade to build the tree of a BDD graph. Several sample designs are presented for logic circuits of NAND, NOR, exclusive-OR, and AND-OR combinational logic. Computer simulation shows that the designed circuits perform the logic operations correctly.
