Which risk increases when resonant frequency drives crystal oscillation?

A)Mechanical stress exceeds fracture toughness
B)Thermoelectric cooling reverses Seebeck effect
C)Excess charge carriers deplete junction
D)Oxidation reduces quantum dot luminosity

💡 Explanation

Mechanical stress accumulates at defects because resonant transfer greatly amplifies displacements; therefore, fracture toughness will be breached under fatigue, rather than thermoelectric reversal being triggered by temperature variation alone.
