← ScienceWhich phenomenon causes decreased carrier mobility in semiconductor alloys?
A)Compositional disorder scattering✓
B)Increased piezoelectric polarization
C)Enhanced radiative recombination
D)Reduced Auger recombination lifetime
💡 Explanation
Compositional disorder introduces potential fluctuations that scatter charge carriers. This scattering increases the effective resistance, hence lowering mobility values because the carriers' mean free paths are reduced; therefore, mobility is reduced rather than increased, affecting alloy performance.
