What is Tunnel diode (Esaki diode)?
A diode with very heavily doped p and n sides that shows negative resistance in forward bias due to tunneling. It was discovered by Leo Esaki in 1957.
Field: PN junctions and diodes
Tunnel diode (Esaki diode) in the explanations
A tunnel diode is a pn junction doped so heavily on both sides that it is degenerate; its depletion region is so thin that tunneling current flows at low forward voltage.
