← ScienceWhich outcome results when a high-frequency signal passes through a tunnel diode's depletion region?
A)Signal amplification via quantum tunneling✓
B)Increased resistance due to barrier widening
C)Signal attenuation via electron scattering
D)Frequency doubling due to harmonic generation
💡 Explanation
When a high-frequency signal is applied, quantum tunneling allows electrons to pass through the thin depletion region by wave function overlap, resulting in a negative resistance region, amplifying the signal. Therefore signal amplification via tunneling occurs, rather than increased resistance or attenuation which require wider barriers or scattering events.
