Silicon 3D detectors consist of an array of columnar electrodes (radius โผ 5ยตm) of both doping types which penetrate entirely in the detector bulk, perpendicularly to the surface. This structure decouples the electrode distance from the sensor substrate thickness. The close electrode spacing provides several advantages compared to the planar sensor design: low full depletion voltage (โผ 10 V),...
