Which outcome arises when applying voltage to tunnel diode?

A)Current decreasing with increasing bias
B)Uniform electron density across junction
C)Increased electron mobility in depletion
D)Reduced thermal noise within diode

💡 Explanation

Applying voltage can initiate quantum tunneling effect of electrons across the thin depletion region, especially under reverse bias, leading to negative differential resistance region. Therefore, current drops as the bias climbs, rather than staying constant because back-diode configurations alter I-V curves.
