Abstract:
A photodetector using a modified ion-sensitive field effect transistor has therein a layer of photoactive material. Upon exposure to a beam of light the photoactive material produces a charge-separation (with proton movement) therein which affects the drain current. The change in gate voltage to stabilizes the drain current is a measure of the intensity of the light input.
