- Does your sensor convert the stimulus directly into electric output?
Silicon detectors consist of n type material while having p type aluminium strips on the surface which are separated by a thin insulator. At the same time there is an electric field between the p strips and the n type material. When a radiation particle passes the detector, silicon atoms are ionized and free electrons leave these atoms with an electron vacancy (holes). After they reach the p type strip they are collected and then create a charge on the aluminium strip which is possible to be measured with special electronics.
