In this paper, we present a model proposition of photo-SET (single electron photo-detector) aiming at detecting one by one electrons. In the first part of this work, we present the two blocs of the proposed photo-SET (reading and detection blocs). The device structure presented is consisting of two SETs capacitively coupled. In this model, the first SET (SET1) is supposed to read the charge whereas the detection bloc is represented by the second SET (SET2). In the second part, we investigate the effects of photoexcitation on I d -V g curves and we present results obtained on the output photo-SET characteristics after variation of power illumination and response time.
