the schemes made by I.K.Kamilov and K.M.Aliev from the combination of several tunnel
diodes [5,6]. Tunnel diodes are widely used in microwave ovens, nuclear weapons, and
aerospace applications. It is very important to generate a large tunnel current from the tunnel
diodes at high temperatures and under the influence of the magnetic field and to reduce the
excess current generated in the tunnel diodes. The resistance of tunnel diodes to external
influences is due to the fact that they are strongly alloyed or prepared from the combination
of various chemical elements by the heterostructure method.
In the work of Professor Paul R. Berger of the University of Ohio in the USA, it was
observed that when the temperature of the GaN/AIN-based two-barresonant tunnel diode is

℃, the current density at the highest point is

, and the voltage
reaches 8 volts [7]. We can observe in experiments that the tunnel current increases with
temperature increase in strongly biased semiconductors, and the tunnel diode decreases
with temperature increase in weak biased semiconductors [8]. A high current density in
tunnel diodes is an indication of the efficiency value of the diode. Based on the above, the
purpose of this work is to study the effects of the magnetic field and the magnetic field on
the transparency coefficient of the tunnel diode VAX and the excess current in the
expression of the total current of the tunnel diode.
2. Calculation of excess current in the tunnel diode according to the model
provided by Chaynovet
According to the model presented by Chaynovet[9], if the field of U'YuCh affects the
excess current in the tunnel diode, we write that the electric field is strengthened in the form

difference, d is the voltage given by the V
