一、序言具有优越能量分辨率的锗、硅探测器已发展到市售水平,各个领域有着广泛应用。探测器发展的目标将是进一步对新材料的研制,使之在常温下的能量分辨率和碘化钠(铊)相同或比它还好,而且处理简单适于作γ射线探测器。一般来说,要在常温下显示出良好的能量分辨率,必须减小泄漏电流 First, the preface Has superior energy resolution of germanium, silicon detectors have been developed to the level of the market, has a wide range of applications in various fields. The goal of detector development will be to further develop new materials so that their energy resolution at room temperature is the same as or better than sodium iodide (thallium), and their handling is simple and suitable for use as a gamma-ray detector. In general, to show good energy resolution at room temperature, the leakage current must be reduced
