Project description
PhotonicQCA aimed to combine the concepts of Quantum-Dot Cellular Automata (QCA) for zero-current logic with chemical functionalisation of quantum dot semiconductor structures and the use of these hybrid structures to enable optical addressing. QCA switch by rearranging charges within a cell, and can be a path to logical circuits that do not require flow of current, but fabrication has been a challenge to date, and addressing of smaller and smaller structures by wiring is also a problem. This project studied novel approaches for fabrication and positioning of quantum dot (QD) structures and chemical functionalization for optical control of the injection and transfer of charge into and between QDs. The project aimed to point the way toward novel QCAs that can be written, clocked and read out optically without the need for electronic nano-micro interfaces; this could create a fully new paradigm for design, fabrication and addressing of logical circuitry.
