In What’s the point?: The Point Contact transistor I discussed Shockley’s white paper on the theory of the Point Contact Transistor. Let’s look further into this early transistor design. It is ...
In his 1948 white paper 1, Shockley wrote, “The theory of the point-contact transistor is that the emitter point-contact introduces holes into the n-type base material. The collector point-contact, ...
There was no doubt about it, point-contact transistors were fidgety. The transistors being made by Bell just didn't work the same way twice, and on top of that, they were noisy. While one lab at Bell ...
65 years ago, December 16th 1947, William Shockley, John Bardeen, and Walter Brattain operated the first ever working point-contact transistor, almost known as the iotatron. Now, so many years later, ...
NATURE ABHORS A vacuum tube," cracked Bell Labs physicist John Pierce. So did almost everyone else by the 1940s. Sure, vacuum tubes boosted the power of the phone network's electrical signals, which ...

What Is a Transistor, and How Does It Work?
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 ...
The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

Beyond the power variant, it sometimes seems as though we rarely encounter a discrete transistor these days, such has been the advance of integrated electronics. But they have a rich history, going ...
