Abstract :
A simple contact structure is proposed for the realization of position sensitive detectors based on a voltage division principle in which the sensors operate in a photoconductive regime. The transfer function of the system is calculated by a detailed analysis of the operative principle of the device. Moreover, the expected performances of the photodetectors are discussed as a function of the main system parameters, underlying the benefits due to the adopted design.
