Which increased risk occurs when exceeding crystal's temperature limits?

A)Increased dopant atom diffusion
B)Increased grain boundary scattering
C)Decreased electron-phonon interactions
D)Decreased impurity band formation

💡 Explanation

Increased dopant atom diffusion results when exceeding thermal limits, because increased temperature causes higher atomic mobility enhancing diffusion rates according to Fick's laws. Therefore dopant profiles broaden, rather than alternatives because they require specific conditions un related to thermal effects.
