Complex Atomic-Scale Surface Electronic Circuit’s Simulator Including the Pads and the Supporting Surface

Abstract

Complex atomic-scale circuits designed in classical, semi-classical and Quantum Hamiltonian Computing approaches using multi-atomic wires interconnects and Au(111) metallic nano-pads contacts discussed in Chapter “The Design of a Surface Atomic Scale Logic Gate with Molecular Latch Inputs” have been investigated to go forward for reaching compact and complex Boolean logic gates systems. The atomic wire electronic band gap, the tunneling intensity decay problems with the length of those atomic-scale interconnects and the practical size of the total atomic-scale circuit are discussed with the future perspective of developing an atomic-scale circuit simulator. Practical problems like the limitation in number of atoms of circuit builders and software limitations in terms of RAM memory and CPU computing time are also discussed for this objective.
