| Popis: | A design modification to an existing border termination for active-edge planar radiation detectors is proposed, which enables a dead area reduction and a much larger breakdown voltage to be achieved, with a minor increase in the fabrication complexity. ‘Technology Computer-Aided Design’ simulations allowed the device performance of different variants of the proposed structure to be investigated also in comparison with the existing one. Among considered designs, the new border terminations with 2(3) guard rings, featuring a dead area at the edge of ∼90(120) μm, can withstand more than 375(500) V for all oxide charge density values up to 3 × 1012 cm−2. These characteristics make them appealing for X-ray imaging applications at free-electron laser facilities. |
