New theory could change the design of future spintronic circuits

The flow of electric charge lies at the heart of electronic circuits. However, electrons also have spin, and flows of electron spin play a vital role in spintronic circuits. These could be essential for our future computing ...

New quantum switch turns metals into insulators

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money ...

Double layer of graphene helps to control spin currents

In order to make transistors that operate using the spin of electrons rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be ...
