title: Logic operations of chemically assembled single-electron transistor.
abstract: Double-gate single-electron transistors (SETs) were fabricated by chemical assembling using electroless gold-plated nanogap electrodes and chemisorbed chemically synthesized gold nanoparticles. The fabricated SET showed periodic and stable Coulomb oscillations under application of voltages of both gates. The sole SET also exhibited all two-input logic operations-XOR, XNOR, NAND, OR, NOR, and AND-with an on/off ratio of 10(2). This demonstrates the potential of chemical assembling to give highly stable SETs exhibiting all logic operations.
