Long antenna in this transistor radio will strengthen the FM signal in somewhere with weak reception. Good quality of AM receiver inside the portable radio.Just keep one to take you to the old days!

Essentially, the ultra-thin layer of insulating material in such small transistors will fail to stop electrons from flowing, and the transistor will no longer function as a switch. However, that ...

On the other hand, all that's really needed is a single electron at a time. A transistor small enough to operate with only one electron would be phenomenally small, yet it is theoretically possible.

The original transistors were small cylinders, a bit larger than a pencil eraser. Over the years, scientists and engineers have been able to make transistors tinier and tinier. With the invention ...
