“…Radiation dose detectors, acquiring crucial energy information on nuclear radiation (X/γ-rays, neutrons, charged particles, etc. ), play an important role in nuclear protection, human cancer therapy, and nuclear accident early warning. − Various detectors (i.e., semiconductor detectors, scintillator detectors, and ionization chambers) have been developed with different principles of measurements and designs, but the application is limited by their respective problems. − Air-filled ionization chambers, which are the golden standard in X/γ-ray dose monitoring, are widely used owing to their high sensitivity, broad measuring range, and stable response but suffer from all-known problems of frequent air density corrections, a high working voltage, and a long stability time. , Therefore, all-solid-state radiation dose detectors based on high-performance materials and structures are in high demand and worthy of in-depth study.…”
