Which risk increases when a doped silicon crystal used in a high-power transistor undergoes rapid thermal cycling?

A)Increased frequency switching speed
B)Formation of Kirkendall voids
C)Enhanced electron mobility
D)Reduced junction capacitance

💡 Explanation

Kirkendall voids increase because repeated heating and cooling promotes differential diffusion rates within the crystal, concentrating vacancies. Therefore, voids form, leading to mechanical stress failures, rather than mobility increases which stable conditions favor.
