WebFeb 25, 2024 · When traversing through a silicon detector, an impinging radiation creates electron–hole pairs along its path. In the presence of an electric field, these charge carriers are separated and start drifting toward the electrodes, thus inducing a current signal [ 4 ], which is fed to an external amplifier. Figure 1.
