← ScienceWhich outcome occurs when impedance mismatches alter traveling electron wavefunction solutions of quantum well heterostructure devices?
A)Increased quantum confinement increases tunneling
B)Scattering reduces electron transmission efficiency✓
C)Wavefunction phase increases group velocity
D)Thermal noise induces energy band mixing
💡 Explanation
Scattering reduces electron transmission because variations in material composition change the wavefunctions allowed within the heterostructure via electron diffraction; therefore, transmission probability decreases, rather than some different condition inducing band mixing.
