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 ...

Scientists create fully electronic 2-D spin transistors

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) ...

Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...
