Which risk increases when semiconductor crystals experience rapid thermal gradients?

A)Increased covalent bond formation rate
B)Reduced electron-phonon scattering events
C)Elevated interstitial defect formation
D)Enhanced piezoelectric charge generation

💡 Explanation

Elevated interstitial defect formation results because rapid temperature changes induce significant stress within the crystal lattice promoting Frenkel defect creation, therefore increasing displaced atoms, rather than enhanced charge generation which requires specific doping or piezoelectricity.
