*6.2. Benchmarking*

Figure 21 compares the performance of various reported GaN-based α-particle detectors as a function of detected energies. About 30% higher CCE was reported for the compensated 15 μm α-particle detectors at −20 V. In addition, compensated detectors also exhibit 96.7% CCE at −300 V, which is 250 V in comparison to other published literature. These promising results pave the way for compensated α-particle detectors to achieve high CCE with low operating voltage.
