Influence of heating of charge carriers on the contact resistance of the Schottky barrier

The influence of heating of charge carriers on the contact resistance of the Schottky barrier is investigated. The current-voltage characteristics of the metal-semiconductor contact were calculated taking into account the heating of charge carriers and it was found that the contact resistance strongly depends both on the temperature of the charge carriers, as well as on the magnitude of the current flowing through the barrier. The nature of the dependence of the resistance on the current is due to the fact that the diode with hot carriers becomes a source of the electromotive force dependent on the current.
