涂有中子反应材料的半导体二极管探测器目前正在进行各种用途的研究，如热中子遥感、快中子计数和热中子照相。理论表明，单涂层器件可以产生4%到11%的热中子效率，这一点得到了实验证据的支持。辐射耐受性测量表明，这些设备的功能良好，达到10/cm的极限热中子注量，超过这一限制，会出现明显的退化。用双列直列式像素设备拍摄的阶梯楔形和简单体模的热中子对比图像显示了热中子成像探测器的前景。
Semiconductor diode detectors coated with neutron reactive material are presently under investigation for various uses, such as remote sensing of thermal neutrons, fast neutron counting, and thermal neutron radiography. Theory indicates that single-coated devices can yield thermal neutron efficiencies from 4% to 11%, which is supported by experimental evidence. Radiation endurance measurements indicate that the devices function well up to a limiting thermal neutron fluence of 10/cm, beyond which noticeable degradation occurs. Thermal neutron contrast images of step wedges and simple phantoms, taken with dual in-line pixel devices, show promise for thermal neutron imaging detectors.
