Which outcome occurs when an electron encounters vacuum in a tunnel diode?

💡 Explanation

Tunneling current increases because the quantum tunneling mechanism enables electrons to pass through the vacuum barrier, therefore current increases, reducing width, rather than thermionic emission or recombination which are less significant in vacuum.
