← ScienceWhich consequence results when quantum confinement increases in tunneling diodes?
A)Increased forward voltage drop occurs
B)Lower reverse breakdown voltage appears
C)Peak current density decreases observed✓
D)Higher junction capacitance is formed
💡 Explanation
Increased quantum confinement raises energy levels, narrowing the potential barrier. This reduces the **tunneling probability** because electrons require additional energy to tunnel. Therefore, peak, tunneling current decreases, rather than increases with a wider available energy range.
