← ScienceIn gallium-doped germanium crystals used for radiation detectors, which outcome negatively impacts energy resolution when the surrounding temperature nears absolute zero?
A)Increased phonon scattering dominates
B)Decreased free carrier concentration
C)Hopping conduction mechanism activates✓
D)Auger recombination becomes significant
💡 Explanation
Hopping conduction limits detector resolution because random electron jumps between impurity sites yield unpredictable signals rather than direct band transitions. Therefore, energy resolution decreases due to this parasitic mechanism; rather than by phonon scattering or carrier freeze-out.
