ABSTRACT:
A directly converting radiation detector with a diode structure having first and second operating electrodes on opposite sides of a semiconductor body has an additional injector electrode, which injects charge carriers for the compensating charged traps in the semiconductor body. The secondary dark current generated in this way does not flow via the electrode used for measurement purposes and therefore does not influence the measured signal. The injection is facilitated by suitable doping under the injector electrode.
