Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the “electric field effect in atomically thin carbon films”. Their work described the extraordinary electronic properties of graphene, a crystalline form of carbon equivalent to a single layer of graphite, just one atom thick.
Around that time, I started my doctorate at the University of Surrey. Our team specialised in the electronic properties of carbon. Carbon nanotubes were the latest craze, which I was happily following. One day, my professor encouraged a group of us to travel to London to attend a talk by a well-known science communicator from the University of Manchester. This was Andre Geim.
