← ScienceWhich conduction behavior results in doped semiconductor crystals?
A)Increased electron-hole recombination rate
B)Formation of excitons due to binding
C)Changes in band structure energy✓
D)Increased phonon scattering near boundaries
💡 Explanation
Doping alters the crystal's elemental composition, which changes band structure energy because impurity atoms introduce new energy levels within the bandgap, therefore modifying intrinsic semiconductor properties rather than just affecting recombination or phonon scattering.
