Ma to su poluprovodnicki senzori uopšteno!
Meni treba MOS tranzistor kao senzor gama zračenja i pogledaj fajl!

a mos je poluprovodnik jelda, a sa gejtom jos laksi posao

A gamma photon, absorbed within a semiconductor detector, generates electrical charge that is proportional to the photon energy and the energy is measurable by full charge collection. Therefore the detector performance depends on the charge collection efficiency. The detector is coupled to an electronic circuit that filters out its leakage current except for the time when the gamma induced charge flows through it. The temporal gamma induced current is much higher than the leakage current that determines the energy resolution.

a ono piše
As a result, a number of electrons are transferred from the valence band to the conduction band,
pa ti onda pogledaš profinu sličicu, kad ono desno ima na slički. pa sabereš 2 i 2.
