Abstract :
The proposed upgrade of the CERN Large Hadron Collider to ten times brighter luminosity poses severe challenges to semiconductor detectors within the CERN experiments. We investigate a silicon "3-D" detector design for these conditions and semiconductors alternative to silicon, namely silicon carbide and gallium nitride. Charge collection measurements suggest some degree of additional radiation tolerance over conventional detector geometry and materials.
