What is it about?

Silicon Carbide Radiation Detectors for Medical Applications There is increasing interest in the development of radiation hard detector materials with the capability to discriminate within wide dose range and high radiation tolerance that are sensitive, and show a linear response. In this study, fabricated 4H-SiC Schottky diodes were exposed to dose rates ranging from 0.02 to 0.185 mGy/min to analyse the linearity and sensitivity at room temperature.

Why is it important?

The realization of a vertical detector structure, coupled with the high quality of epitaxial layers, has resulted in a linearity and sensitivity of the detector that is significantly higher than those published previously for moderate dose rate testing.
