A new batch of microdosimeters has been extensively studied for their charge collection efficiency (CCE) properties, as well as their radiation hardness for medical, space and accident applications. Silicon-on-insulator (SOI) microdosimeters with an active layer thickness of 10, 20 and 50 μm have been investigated and were characterized with a 24 MeV carbon ion beam as well as a Co-60 gamma source. A negative pulse was observed in addition to the positive pulses generated within the sensitive v...

Two-dimensional materials are interesting since they are atomic layer thin films that may be electrically pushed into vibration and function as nano-electromechanical resonators (NEMS) with characteristic resonance frequencies exceeding 100 MHz and typically ultrahigh quality characteristics at low temperatures.
