Can anyone explain this sentence about tunneling transport process? it is not true that in-plane momentum needs to be conserved. As there is a scattering region, the momentum along the direction of transport is no longer a good quantum number. what mean's "a good quantum number"?

Hi,
Along the transport direction, we do not assume the periodic boundary condition. Thus, the wave functions do not follow the form of Bloch functions along the direction anymore, implying that the momentum cannot be regarded as a good quantum number.
