← ScienceWhich outcome results when doping silicon within tunnel diodes?
A)Increased electron tunneling probability✓
B)Decreased device breakdown voltage
C)Augmented lattice vibrational frequency
D)Reduced electron effective mass
💡 Explanation
Doping creates a narrow depletion region, narrowing the region that electrons must tunnel through; *quantum tunneling* becomes more probable because the barrier width is reduced, therefore electron tunneling probability increases, rather than decreasing from an increased barrier width.
