Abstract :
In order to explain the experimentally found non-uniformity of the dark currents corresponding to different pixels of a video-camera chip, there were accomplished: a) a numerical study of the temperature dependence of the dark currents, in order to find the most convenient theoretical model which can describe sufficiently accurate the experimental data, b) the evaluation of the basic parameters of the studied pixels, corresponding to the chosen theoretical model, c) the study of the correlation between these parameters and their implications on the temperature dependence of the dark currents non-uniformity for different pixels of the studied chip.
