The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing ‘made-to-order’ materials and more energy-efficient electronics.

We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like. Today’s silicon-based electronics, however, consume a substantial and ever-increasing share of the world’s energy.

A number of researchers are exploring the propert...
