Episode notes
Vacuum Tubes Before Transistors
- Vacuum tubes were crucial but large, power-hungry, and fragile components before transistors.
- They enabled amplification, switching, and rectification but limited electronic device miniaturization.
Birth of the Transistor
- The first transistor was invented at Bell Labs by Bardeen and Bratton in 1947 using a germanium crystal.
- Shockley later improved it with a more practical junction transistor design, enabling mass production.
Transition to Silicon Transistors
- Early transistors used germanium, but silicon proved superior due to abundance and heat resistance.
- Silicon transistors became key for military and industrial applications, leading to widespread commercial growth.
