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 wanted ...

The diode showed no resistance in the forward direction, normal resistance in the backward direction, and it worked with zero applied magnetic field. The research to date has been done at extremely ...

A team of researchers led by the University of Pittsburgh demonstrated a programmable superconducting diode at the LaAlO 3 /KTaO 3 (LAO/KTO) interface, an advance that holds potential to enhance/help ...

As electronic devices become ever more complex, and the densities of components in those devices increases exponentially, we are rapidly approaching the day when the limitations of Moore's Law will be ...

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics: thermionic ...

What would happen if you combined the unparalleled efficiency of a superconductor with the flexibility and controllability of a semiconductor? Thanks to a new breakthrough in quantum materials, we may ...

Scientists have reviewed the superconducting diode effect, a quantum effect enabling dissipationless supercurrent to flow in only one direction. The SDE provides new functionalities for ...
