Description

The organometal halide perovskites (OMHP) semiconductors have been proven in the recent years to be promising material to detect ionization radiation, beside the well known success as photovoltaic devices.
In particular, OHMPs show large potential for X-rays detection due to their high stopping power, especially for energy above 30 keV where the Silicon absorption coefficient starts to decrease.
In this talk I will show preliminary results from the Micro-Perov and HyPoSiCX (Hybrid Perovskite on Silicon CMOS X-ray Detectors) projects.
I will focus on novel techniques which enable the deposition and growth of OHMPs crystals of micrometer dimensions directly on patterned conductive substrate with precise positions and dimensions.These techniques are attractive for X-ray pixelated detectors and opens the possibility to integrate OHMPs with CMOS technology.
