Which consequence results when nitrogen atoms contaminate silicon crystal?

A)Reduced electron mobility occurs overall
B)Increased thermal expansion coefficient results
C)Enhanced piezoelectric behavior develops then
D)Increased dielectric strength gets expressed

💡 Explanation

Doping introduces energy levels which scatter moving electrons; therefore electron mobility is reduced because electron scattering increases through Impurity scattering, rather than creating piezoelectricity, which require specific crystal structures.
