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.

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 ...

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 ...

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 ...

"For years we have seen limits to how small transistors can get," said Moore in an Intel press release. "This change in the basic structure is a truly revolutionary approach, and one that should ...
