Nature Physics - Nanoscale engineering can now take advantage of a new ratchet device: it acts as a diode for superconducting vortices, but its directionality can be controlled and repeatedly ...

Alexey Kavokin is at the Dipartimento di Fisica, University of Rome II “Tor Vergata”, and at the Physics and Astronomy School of the University of Southampton, Highfield, Southampton, SO17 1BJ ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

This second course provides a more detailed description of high-voltage Schottky and p-n diodes, starting with the semiconductor physics background needed to analyze both types of diodes. The main ...
