← ScienceWhich mechanism causes limited current flow within silicon-based semiconductors?
A)Presence of the band gap✓
B)Increased electron-phonon scattering
C)Material work function mismatch
D)Auger recombination at high bias
💡 Explanation
The presence of the band gap limits current flow, because electrons require energy to jump this gap and conduct. Therefore, only electrons with sufficient energy can contribute, rather than those hindered by scattering or surface conditions.
