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.

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 ...

was the point-contact transistor. William Shockley improved on this design with his junction transistor, a three-layer sandwich of different types of semiconductor. The diagram illustrates the ...
