← ScienceWhich outcome occurs when a heavily doped silicon nanowire's depletion regions fully merge?
A)Increased electron tunneling conductivity✓
B)Reduced electron-hole recombination rate
C)Increased phonon scattering and heating
D)Reduced depletion capacitance and charge storage
💡 Explanation
When depletion regions merge throughout the nanowire, quantum tunneling occurs because the barrier width diminishes, enabling electrons to tunnel through the potential barrier, increasing conductivity. Therefore, tunneling conductivity increases, rather than reduced recombination, increased scattering, or reduced capacitance which require different conditions to arise.
