← ScienceWhich constraint arises when doping modulates a crystal lattice?
A)Reduced carrier scattering mobility✓
B)Increased phonon transmission efficiency
C)Enhanced intrinsic thermal conductivity
D)Decreased exciton formation probability
💡 Explanation
Doping introduces impurities into the lattice, causing increased phonon scattering mechanism impacting carrier mobility because charge carriers collide more frequently with lattice imperfections; therefore, mobility is reduced rather than other transport properties being enhanced in a doped lattice.
