W GaN converter from STMicroelectronics targets fast chargers, adapters, and power supplies for home appliances.

This extreme level of control enables SETs to achieve unprecedented levels of miniaturization, sensitivity, and energy efficiency. Schematic of a Single Electron Transistor (SET). Because of the small ...

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.

In the case of Brattain's transistor, current flowed towards the second gold contact. Think about what that means. A small current in through one contact changes the nature of the semiconductor so ...
