The temperature dependence of the tunneling current is calculated in terms of this change in barrier height. The explanation is offered as a solution to the previous inconsistences between experimental data and the calculations based on the temperature dependence of the Fermi-Dirac distribution function of the conduction electrons in the electrodes. Abstractde Die logarithmische Leitfähigkeit von AlAl2O3-Metall-Tunnelschichten zeigt, daß die Austrittsarbeit Φ Metall-Isolator mit steigender Temperatur abnimmt. Die Temperaturabhängigkeit des Tunnelstroms unter Berücksichtigung der Temperaturabhängigkeit der Austrittsarbeit Φ wird berechnet. Das Resultat erklärt die früher wiederholt beobachtete Diskrepanz zwischen Messungen und der Rechnung, die nur die Temperaturabhängigkeit der Fermi-Dirac'schen Verteilungsfunktion der Leitungselektronen in den Metallen berücksichtigte.
