where the first term of the above expression gives the tunnel diode current and
the second part gives normal thermal current of a p-n junction diode. The
negative differential resistance can be obtained from the derivative of the first
term.

ELECTRONIC DEVICES AND APPLICATIONS
6.7 TUNNEL DIODE Tunnel diode was invented by the Japanese scientist L.
Esaki in 1958. The tunnel diode works under the principle of quantum-
mechanical tunnelling. We know that an electron has a dual nature: it behaves
both as.
