Low-Voltage p-i-n GaN-Based Alpha-Particle Detector With High Energy Resolution

The pursuit of low power consumption, high charge collection efficiency (CCE), and high energy resolution is critical for the development of high performance GaN-based alpha-particle detectors. In this letter, we fabricated a low-voltage p-i-n GaN-based alpha-particle detector with superior energy resolution. The detector exhibits a very low leakage current of pA level even at −100 V and high CCEs...
