Transistors need barriers. When electrons start tunneling through these barriers, you get problems. Big problems. In fact, quantum tunneling sets a fundamental limit on how small transistors can get.

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 ...

The function of the transistor is to utilize the voltage applied to the gate to control the current flow between the drain and source. Upon applying a small voltage to the gate, it permits a large ...

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.

Is Moore's Law really dead? How small can a transistor be? And what in the world is "dark silicon?" Read on to find out. Named for Intel co-founder Gordon Moore, Moore’s Law is the observation ...

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 ...
