TYPE OF EXCESS CURRENT GENERATED IN TUNNEL DIODES AND BARRIER TRANSPARENCY COEFFICIENT (TRANSFER COEFFICIENT) IN DIFFERENT MODELS

Abstract

In this work, the transparency coefficient of the barrier formed in a tunnel diode was investigated by adding it as a variable in the Tsu - Esaki model. Also, the excess current generated in the tunnel diode was analyzed with the Chynowez model, based on th e theory of Knott and Demass. Based on the Franz -Keldesh model for various values of the electric field, the current - voltage characteristic of the tunnel diode was obtained from the change in the excess current of the tunnel diode
