An international research team led by physicists at the University of California, Riverside, has revealed a new quantum process in valleytronics that can speed up the development of this fairly new technology.

Valleytronics, a portmanteau of "valley" and "electronics," uses local energy minima—or valleys—in the electronic band structure of semiconductors. Current semiconductor technology uses electronic charge or spin to store and process information. In some semiconductors, however, valleys of the electrons are used to encode, process, and store information. Valleytronic systems have the potential to offer information processing schemes that are superior to charge- and spin-based semiconductor technologies.
