Annotation The accuracy of the main qualitative barrier transitions characteristics (barrier height b and nonideality factor η) depends on the accuracy of the measurement as the current and voltage as their determination method. The methods for determining the Schottky barrier height using current-voltage characteristics are considered and tested at the Ag/n - n+GaAs barrier transitions, which are made using different heat treatment regimes. It is established that the method of calculating the current-voltage characteristics by the Rhoderick method is the simplest, but it does not take into account the series resistance, which can lead to additional errors in determining the current-voltage characteristic section where this influence can be neglected. It is established that the most accurate method is the direct approximation method, which takes into account the effect of the series resistance in calculating the non-ideality factor and the Schottky barrier height.
