To confuse you even more I seem to remember in the dim and very
distant past the first time a transistor was demonstrated it was an
electrolytic one with three electrodes in a solution. Definitely pre
germanium times. I think look in an old scientific american late1940s.
Electrolytic diodes were quite common in the 1930s they could handle
quite high current.
Aluminium rod and a copper rod immersed in sodium bicarb solution.
Real simple.
