Episode 7: Electronics

Transistor

We don’t normally think of computers, radios, and cell phones as products of chemistry, but none of these devices would be possible without specialized chemical manufacturing components and techniques. The integrated circuits at the heart of these tools depend on the unique electrical properties of certain inorganic elements such as silicon, germanium, and gallium. On today’s show we speak with Henry Kressel, author of Competing for the Future: How Digital Innovations Are Changing the World, about the early solid-state transistors that heralded the beginnings of the Digitial Age. We also share some listener feedback. The Element of the Week: Germanium.
