They have none of the special skills you’d find in tunnel, Gunn, varicap, Zener, and avalanche diodes, or even LEDs, instead they are simply a one-way valve for electrical current. Connect ...

The four-layer diode, therefore, could be used to replace both the rectifiers and transistors necessary to connect long distance phone calls. In essence, the four-layer diode was the first ...

The oxide forms between the electrolyte and the aluminum, providing the diode’s junction. Connections are made to the soldered copper and to the aluminum. To truly try it out he put together a ...
