← ScienceWhich mechanism causes decreased hole mobility in semiconductor lattices?
A)Increased phonon density induced impedance✓
B)Reduced electron-hole recombination spacing
C)Enhanced piezoelectric potential generation
D)Decreased band structure effective mass
💡 Explanation
Increased phonon density in the lattice disrupts hole movement via phonon scattering, because the thermally induced vibrations impede unobstructed hole transport, therefore reducing mobility rather than enhancing it via other mechanisms.
