| contents | Currently, the X-ray detectors are widely used in medical imaging, industrial inspection, aerospace, and other fields, as the market demand for high-efficiency, flexible, and low-power detectors is increased. Although the traditional inorganic X-ray detection materials have achieved great success and effectiveness, they have their own limitations and let alone flexibility/bendability and memory function. In this study, we present the design of a BiSeI/NiO-based X-ray synaptic detector and its application in the simulation of biological synaptic processes. Herein, the BiSeI, a quasi-1D inorganic semiconductor, stands out as an ideal choice for the X-ray detectors, especially for flexible and portable devices due to its large atomic number, large photoelectric absorption coefficient, and mechanical plasticity. Meanwhile, the NiO-based materials provide the memory function required for the intelligent detection systems. Moreover, our devices offer notable advantages in terms of low power consumption, compared with traditional X-ray detectors. The BiSeI/NiO detectors demonstrate advanced features with an ultrahigh sensitivity, an ultralow detection limit, and include the paired-pulse facilitation (PPF) and the transition from short- to long-term memory, maintaining the functionality on flexible substrates. This design represents a significant step toward the development of intelligent and flexible X-ray detectors. |
