In quantum mechanics, the ability of electrons (negatively charged particles orbiting the nucleus of an atom) to exist in two places at once, in particular on both sides of a barrier. Tunneling allows some of the electrons to effectively move through the barrier and accounts for the "semi" conductor properties of a transistor.
