Wide bandgap semiconductor detectors
- Thomas Bergauer (Austrian Academy of Sciences (AT))
In this talk an overview of the advantage of silicon carbide detectors will be presented in terms of leakage current, signal resolution and radiation hardness. To obtain high performance in the detectors for different applications, new growth process of the epitaxial layers have been developed and the characteristics of the epitaxial layers have been obtained by electrical measurements....
Silicon Carbide (SiC) detectors are gaining renewed research interest alongside the material's growing adoption in power electronics. The physical properties relevant to power electronics are also advantageous for detector applications, and SiC timing detectors could replace silicon detectors in the future. One limitation of SiC, however, is the currently limited epitaxial thickness that can...
The main challenge in radiotherapy (RT) is to deliver a sufficiently high curative dose to the tumour while maintaining tolerable doses to nearby organs at risk, and new treatment modalities are rapidly emerging. FLASH radiotherapy delivers a therapeutic dose several orders of magnitude faster (≥ 40 Gy/s) than conventional RT (0.05 Gy/s) and has been shown to reduce the likelihood of...
Many technologies initially developed for particle physics are now employed in medical particle beam therapy. One area where technology transfer is more challenging is particle sensing, as requirements differ substantially. While particle physics requires detecting and characterizing every particle hitting the detector, only the beam's statistical properties are important in ion beam therapy....
Pristine and neutron-irradiated silicon carbide (SiC) detectors were systematically characterized using the Two-Photon Absorption Transient Current Technique (TPA-TCT) at the laser facility of the University of the Basque Country (UPV/EHU). The investigated SiC detectors are p-in-n diodes, fabricated at IMB-CNM, with an active thickness of 50 microns.
Our study reveals a radiation-induced...
