the Shockley Diode could do more than a transistor. For one, it acted like a rectifier, able to turn alternating current into direct current. Two, it switched on and off when a specific amount of ...

With a slender sheet of lab-grown bismuth and an architecture unlike anything inside today’s silicon chips, they’ve built ...

This kind of thinking would be as important as science for the invention of the transistor ... for radio sets which needed to turn alternating current into direct current. The vacuum tube didn ...
