← ScienceWhich phenomenon limits semiconductor transistor channel conductivity due to surface orbital interactions?
A)Quantum tunneling through barrier
B)Surface scattering of charge carriers✓
C)Electromigration induced voiding
D)Phonon-mediated resistance oscillations
💡 Explanation
When electrons travel through the narrow channel, surface scattering occurs because surface atoms have incomplete orbital bonding, creating defects that disrupt electron trajectories, increasing resistance and limiting conductivity. Therefore surface scattering limits conductivity, rather than tunneling, electromigration, or phonon oscillations, which involve different mechanisms.
