it’s a picture of those earliest transistors, which were point contact devices. A piece of germanium as the base had two metal electrodes touching it as the emitter or collector, and as [Marcin ...

Instead of bothering with tiny wires, Brattain attached a single strip of gold foil over the point of ... of Brattain's transistor, current flowed towards the second gold contact.

Then in December, 1947, in a combination of brilliant theoretical insight and serendipitous accidents, Bardeen and Brattain produced the world’s first semiconductor amplifier—the 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 ...

On December 16, 1947, they demonstrated the first working transistor, now known as the point-contact transistor (a feat for which they were awarded the 1956 Nobel Prize in Physics). The first ...

The same is true for the point contact transistor invented in 1947 at Bell Laboratories. With the arrival of the bipolar (buried) junction transistor in 1951, contact pressure effects on ...

Five years before the first point-contact transistor was invented back in 1942, Isaac Asimov postulated artificially intelligent robots. It took another 40 years or so for rudimentary AI systems ...
