If I say ‘diode’ you probably think silicon diode but there were others before silicon. Germanium also comes to mind and they still have special uses today. There were also vacuum and metal oxide diodes in common use before silicon became mainstream. This is a short video on the insides of a selenium bridge rectifier package and a brief look at the metal oxide semi-conductor.
