BGaN detectors, which are expected to be used for nuclear instrumentation system, demand high temperature and high radiation tolerance. In this study, BGaN with low B composition and high crystallinity were used to improve the characteristics for high tolerance BGaN detectors. The improved detection properties were confirmed in devices using BGaN with a BN mole fraction of 0.45%.
