← ScienceWhich outcome develops when impurities enter a silicon crystal lattice?
A)Increased electrical conductivity (doping)✓
B)Decreased structural integrity (fracture)
C)Enhanced thermal expansion (instability)
D)Reduced optical transparency (absorption)
💡 Explanation
Increased electrical conductivity is observed via doping, caused by substituting atoms that alter carrier concentration therefore altering the band gaps. This occurs because the added impurities contribute extra electrons/holes, rather than causing immediate structural damage or altered optical properties.
