Description
Studies of the silicon dioxide (SiO2) passivation layer in n-on-p silicon sensors, which will be used in the CMS High Granularity Calorimeter (HGCAL), are important for improving their performance not only in High-Luminosity LHC run, but also in future high-energy physics experiments. This work explores a novel method for estimating surface damage in HGCAL sensors. Test diodes with different SiO2 variants were irradiated with X-rays, and their characteristics were measured at controlled temperature of -20ºC. The results are then compared with previous measurements with MOS and strip-like sensors
