← ScienceWhich risk increases when an electron-tunnel-diode is excessively miniaturized?
A)Increased reverse current leakage✓
B)Reduced peak current density
C)Increased forward voltage drop
D)Reduced temperature instability
💡 Explanation
Increased miniaturization raises doping concentrations, narrowing the depletion region, because this enhances **quantum tunneling**. Therefore reverse current leakage increases significantly, especially at lower voltages, rather than improved stability, due to more tunneling events.
