Which mechanism initiates fusion in a tunnel diode?

💡 Explanation

Fusion, or electron movement, occurs by quantum mechanical tunneling because electrons pass through the depletion region energy barrier despite insufficient energy. Thermionic emission requires higher temperatures rather than band bending allowing tunneling.
