Abstract
In radiation sensitive detector devices such as direct conversion detectors charges are drifting within an externally applied electric field towards collecting electrodes (4) which are segmented (e.g. representing a pixel array). At the gaps between segments electrical field lines can leave the detector and charges drifting along those field lines can be trapped within the gap. This can be avoided by external electrodes (8) which push electric field lines back into the direct conversion material.
