In a non-rectifying Schottky barrier, the barrier height is not high enough to form a depletion region. So the depletion region is negligible or absent in the Schottky contact diode.

Tunnel diode is correct answer. Schottky diode is made.
Expand of metal and n type material. So it has no depletion layer.
Expand of metal and n type material. So it has no depletion layer.

Schottky Diode acts like there is no depletion region. So D is correct.

Tunnel diode is highly doped as it contains more number of carriers. I think it has very thin depletion layer.

Tunnel diode has degenerated p and n, so it has very narrow depletion region.

Schottky diode is a combination of metal and the n-type semiconductor. Because it has very small depletion width.

Tunnel effect will have narrow depletion layer because of tunelling effect.
