Defects in these devices result in the spillover of charge into neighboring elements, a process known as "blooming," and the optimal dynamic range of these devices is limited by the existence of dark current.
In the interline variety of these devices, readout occurs by shifting charge to a neighboring hidden column, while full-frame versions of these devices read out the entire data set at the same time, leading to longer readout times. Defects in these devices result in the spillover of charge into neighboring elements, a process known as "blooming," and the optimal dynamic range of these devices is limited by the existence of dark current. The operating principle of these devices is that an incoming photon excites an electron out of a charge well, allowing that electron to be read out; accordingly, these devices are characterized by their well depth and their pixels can be damaged via ionizing radiation. They are generally preferable in scientific applications to CMOS sensors because of their excellent quantum efficiency. For ten points, identify these semiconductor devices which are used heavily used in astronomical imaging.
