← ScienceWhich consequence results when applying substantial voltage to an electron tunneling diode at cryogenic temperatures?
A)Zener breakdown induced electron avalanche
B)Suppressed electron thermal energy increase✓
C)Amplified longitudinal optical phonon emission
D)Increased electron-electron collision rate
💡 Explanation
Applying voltage influences the `tunneling probability` and therefore limits transmitted current. Because electrons cannot fully thermalize due to suppressed lattice vibrations at cryogenic temperatures and voltage, their thermal energy increase is limited, rather than avalanche, emission, or collision rates increasing.
