中文摘要
本文研究了不同过渡金属氧化物在x射线照射下的持续光导(PPC)行为。我们澄清了轨道有序态是PPC的先决条件。此外,晶粒尺寸和晶界对多晶样品的PPC行为有显著影响。为了将PPC应用于辐射探测器,对粒子大小的控制是非常重要的。
英文摘要
We investigated persistent photoconductive (PPC) behavior of various transition-metal oxides under X-ray irradiation. We clarified that the orbital ordered state is the prerequisite for the PPC. In addition, it was revealed that particle size or grain boundary significantly influence the PPC behavior in the polycrystalline samples. In order to apply the PPC to radiation detectors, control on the particle size is very important.
