← ScienceWhich risk increases when hydrostatic pressure narrows an intrinsic semiconductor's band?
A)Increased avalanche diode reverse recovery
B)Augmented material phonon generation
C)Elevated probability of Zener tunneling✓
D)Decreased second breakdown susceptibility
💡 Explanation
Elevated pressure reducing the band gap distance increases Zener tunneling activity because quantum tunneling probability exponentially scales with decreasing barrier width; therefore Zener tunneling becomes more likely, rather than decreased diode recovery, or changed breakdown otherwise controlled by doping factors.
