← ScienceWhich outcome results when silicon doping inhibits electron delocalization?
A)Increased covalent framework bond strength
B)Reduced electron mobility in lattice✓
C)Enhanced Debye Length screening effect
D)Greater orbital hybridization availability
💡 Explanation
Reduced electron mobility occurs because doping disrupts electron delocalization, preventing the formation of extended molecular orbitals throughout the silicon lattice. Therefore, conductivity diminishes, rather than enhancing covalent bond strength or Debye screening since these depend on other bonding properties.
