摘要

我们报告了通过甲基溴化铅铵单晶装置探测到的约数百兆电子伏的高能电子，其灵敏度低至单个电子。在该装置中，释放的能量接近于最小电离粒子释放的能量。这是首次展示可用于跟踪和计数最小电离带电粒子的基于包晶的装置。该装置在 5 V 的低偏置电压下就能达到单粒子灵敏度。它还显示出在约 10^4 的动态范围内，响应与电子数的函数具有良好的线性关系。

Direct detection of minimum ionizing charged particles in perovskite single crystal detector with single particle sensitivity

We report the detection of high energy electrons of some hundreds of MeV, crossing a methylammonium lead bromide single crystal device with sensitivity down to single electrons. In the device, the released energy is close to the energy released by minimum-ionizing particles. This is the first demonstration of a perovskite-based device that can be used for tracking and counting minimum-ionizing charged particles. The device reaches the single particle sensitivity with a low bias voltage of 5 V. It also shows a good linearity of the response as a function of the number of electrons in a dynamic range of approximately 10^4.
