Quantum-Dot Cellular Automata - Experimental Demonstration of a Functional Cell

Abstract

The experimental demonstration of a basic cell of Quantum Dot Cellular Automata, a transistorless conmutation paradigm is presented. The device studied is a six-dot quantum dot cellular system consisting of a four-dot QCA cell and two electrometer dots. The system is fabricated using metal dots, connected by capacitors and tunnel junctions. The operation of a basic cell is confirmed by the externally detected change of the cell polarization controlled by the input signal. The cell exhibits a bistable response, with more than 80% charge polarization within a cell.
