Thermionic Devices and Computing

Before the widespread use of semiconductors, it was possible to compute data electronically using thermionic devices such as valves. These had a number of of functional inadequacies and were eventually superseded by the more compact and reliable solid state alternatives (transistors, diodes and integrated circuits).

The slides outline this progression, including the transition from germanium to silicon.
