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.

Scientists from the University of Glasgow have made a major breakthrough that could lead to a new generation of powerful and ...

"It is too early to promise graphene supercomputers," adds Geim. "In our work, we relied on chance when making such small transistors. Unfortunately, no existing technology allows the cutting ...

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 ...

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 ...

A landmark development led by researchers from the University of Glasgow could help create a new generation of diamond-based ...

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 ...

Glasgow University researchers have led work that could lead to a new generation of diamond-based transistors.
