It might, for example, allow electrons to leak to places where they are not wanted via a process called quantumtunnelling.
比如说，这样很可能会让电子通过一种叫做量子隧道的过程进入不需要它们的区域。

A number of groups of academics and engineers, for example, are pondering how to make transistors in which quantumtunnelling is a feature rather than a bug.
The sensors rely on quantumtunnelling, in which electrons take journeys that would not be allowed by the laws of classical physics, as long as the distances involved are tiny.
