    Study of Si detectors for radiation tolerance at extreme fluences up to 1e18 neq/cm2 has been suffering from numerous challenges. Defects created in the crystal lattice, compensate the doping by trapping the free charge carriers, causing the depletion region to collapse, resisting the utilization of conventional electrical characterization tools. Infrared absorption measurements are still...

    Doping removal is one of the key radiation-damage mechanisms affecting the performance of Low Gain Avalanche Diodes (LGADs). In standard p-type LGADs, the degradation of the gain implant motivated detailed studies of acceptor removal at high initial doping concentrations, of the order of $10^{16}$ $\text{cm}^{-3}$. More recently, the development of new LGAD architectures, such as resistive...

    The demand for radiation-hard 4D detectors capable of simultaneous high-precision timing and spatial resolution is driving the investigation of 4H-Silicon Carbide (4H-SiC) as a robust alternative to silicon. While 4H-SiC offers superior thermal stability and radiation tolerance, its wide bandgap and current epitaxial thickness limits necessitate the use of internal charge multiplication. This...
