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 study was published in the journal PRX Energy. For almost 80 years, the Shockley diode equation has described current flow through solar cells, which power homes and charge battery banks.

While one lab at Bell was trying to improve those first type-A transistors, William Shockley was working on a whole different design that would eventually get rid of these problems. Early in 1948 ...
