To increase the radiation detection efficiency of heterojunction organic photodiode, we fabricated nano structures between the n-type and p-type layers. From the X-ray irradiation experiments, it has been shown that the X-ray induced current increased by 23 % compared with the device without the nano structure. However, as the device properties were different between the fabrication batch processes, investigation of the fabrication process should be continued.Effect of the crystallization of the device has been studied with changing the cooling time after the annealing process of the device. When the cooling time was set to 150 minutes, the X-ray induced current was at maximum value. Further study is necessary to know the best fabrication process.

为了提高异质结有机光电二极管的辐射探测效率，我们在n型和p型层之间制作了纳米结构。X射线辐照实验表明，与不具有纳米结构的器件相比，器件的X射线感应电流增加了23%。然而，由于不同的制备批次工艺的器件性能不同，制备工艺的研究还有待继续。研究了在器件退火热处理后改变冷却时间对器件结晶的影响。当冷却时间为150分钟时，X射线感应电流达到最大值。需要进一步的研究才能知道最佳的制造工艺。
