Valleytronics Shift (IMAGE) Massachusetts Institute of Technology Caption Faster, more efficient data storage and computer logic systems could be on the horizon thanks to a new way of tuning electronic energy levels in two-dimensional films of crystal, discovered by researchers at MIT. The discovery could ultimately pave the way for the development of so-called "valleytronic" devices, which harness the way electrons gather around two equal energy states, known as valleys.
