Which process initiates current flow through a tunnel diode?

💡 Explanation

Quantum tunneling allows electron passage even when energy is lower than the potential barrier because the wave function penetrates the barrier, therefore current flows at lower voltages rather than requiring thermal excitation to surmount the barrier.
