Transistors of the early 1950s primarily used germanium crystals. But by the latter half of the decade, silicon—a more stable semiconductor, abundant in sand—had begun to take over as the material of ...

On Oct. 3, 1950, three scientists at Bell Labs in New Jersey received a U.S. patent for what would become one of the most important inventions of the 20th century — the transistor. John Bardeen, ...

Probably the most important invention of the 2oth Century was the transistor. The first point contact transistor shown below was made at Bell Laboratories. The workbench of John Bardeen and Walter ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...
