I How do electronics in tranistors tunnel if decohered

[jaydnul]

A BJT requires the electrons to tunnel between collector and base to conduct main channel current. But since these electrons are not coherent, how are they tunneling if their quantum properties are gone?

 

[Jilang]

Why do you think they need to be coherent with each other? Tunnelling is not a feature of intererfence.

Loss of coherence does not mean loss of "quantum properties".

 

[jaydnul]

But if the electron's superposition of possible locations is removed, doesn't that remove the probability of it tunneling to the other side?

Loss of coherence doesn't do that.
