← ScienceWhich outcome occurs when applying a gate voltage altering ZnO nanowire orbitals?
A)Increased electron mobility via band bending✓
B)Decreased piezoelectric response diminishes output
C)Enhanced phonon scattering impairs conductivity
D)Reduced chemical reactivity hinders catalysis
💡 Explanation
Increased electron mobility occurs because the gate voltage induces band bending which alters the ZnO nanowire's electron orbital distribution increasing charge carrier concentration and therefore mobility, rather than the piezoelectric, scattering mechanisms, or affecting surface chemistry.
