Graphene Enables Next Step Towards the Age of "Valleytronics"

Graphene Enables Next Step Towards the Age of "Valleytronics"

Researchers at the Penn State Materials Research Institute have fabricated a device made from bilayer graphene that is able to control the momentum of electrons . The result is a less energy intensive approach to computing and a new path for digital logic that leverages a new field of electron physics known as “valleytronics .” Valleytronics is a portmanteau in which the word “valley” refers to an additional degree of freedom for electrons. Electrons are commonly manipulated based on the two degrees of freedom (or properties) that have made possible our computer age: charge and spin. Electronics have long exploited the charge of electrons to make devices that can turn on or off. And more recently, we have also seen the spin of electrons leveraged; scientists have dubbed circuits based on this property spintronics . Both electronics and spintronics have their strengths and ...
