Abstract
Driven by the demand of various applications for a
detection area that is larger than the active area of a
single detector module, we explore the possibility to
realise a large-area detector by a seamless tessellation
of multiple detectors. This requires sensors with a
minimum amount of dead area at the edge. In order to be
able to reduce this area, edge effects must be understood
and avoided or mitigated. In this paper, we report on
first tests that are performed on diamond-blade diced
slim-edge pieces of cadmium telluride with a
last-pixel-to-edge distance of only 65 µm. The results
indicate that the edge-pixel response is not
significantly affected with respect to the leakage
current and the charge collection efficiency. First
measurements towards a quantification of the detective
quantum efficiency have been made on edge pixels by
determining the pixel response function and the noise
power spectrum
