← ScienceWhich consequence results when exceeding the thermal limit in gallium-doped germanium?
A)Intrinsic carriers begin to dominate✓
B)Superconductivity abruptly becomes evident
C)Ferromagnetic order abruptly collapses
D)Quantum tunneling probability diminishes
💡 Explanation
Exceeding its thermal limit generates intrinsic carriers, where thermal energy provides enough energy to overcome the band gap, because electrons begin to jump from the valence band to the conduction band. Therefore intrinsic carriers dominate conductance rather than impurities, altering semiconductor behavior.
