Which outcome limits conductivity during doping with solid ionic compounds?

A)Increased scattering of charge carriers
B)Enhancement of electron-phonon interactions
C)Destructive quantum interference effects
D)Suppression of the polaron formation

💡 Explanation

Increased scattering limits conductivity because lattice defects introduced during doping act as scattering centers, impeding the movement of charge carriers, reducing overall conductivity rather than enhancing it. Therefore it is caused by defects; rather than phonon or band gap modifications.
