← ScienceWhich outcome occurs when a silicon crystal contains excess phosphorus?
A)Increased electron conductivity✓
B)Decreased hole concentration
C)Limited current capacity
D)Induced piezoelectric effect
💡 Explanation
Excess phosphorus donates electrons, increasing conductivity because the doping mechanism overwhelms the silicon’s intrinsic carrier concentration; therefore, electron conductivity rises, rather than hole concentration decreasing or a piezoelectric effect being induced.
