Professor Lee Cronin at the University of Glasgow said, “What we have done is find a way to potentially increase the data storage capabilities in a radical way. We have been able to assemble a functional nanocluster that incorporates two electron donating groups, and position them precisely 0.32 nm apart so that they can form a totally new type of molecular switching device. The key advantage of the molecule sized switch is information / transistor density in traditional semi-conductors. Molecule sized switches would lead to increasing data storage to say 4 Petabits per square inch. This breakthrough shows conceptually that this is possible (showing the bulk effect) but we are yet to solve the fabrication and addressing problems. The fact these switches work on carbon means that they could be embedded in plastic chips so silicon is not needed and the system becomes much more flexible both physically and technologically.”
