← ScienceWhich mechanism causes increased conductivity when cooling certain perovskite materials?
A)Polaron delocalization enables wider band transport✓
B)Reduced piezoelectricity diminishes electron scattering
C)Increased ferromagnetism improves spin alignment
D)Enhanced pyroelectricity increases charge separation
💡 Explanation
Polaron delocalization creates electronic band widening that enables wider band transport because electrons behave as free carriers within a wide and smooth potential, rather than strongly localized bound state. Therefore conductivity increases, rather than diminishes with piezoelectricity.
