砷化镓探测器 meaning in English
gaas detector
gallium arseide detector
galliumarsenide detector
Examples
- Gallium arseide detector
砷化镓探测器 - After measuring dark current , photocurrent and response to x pulse of gaas detector before and after 1 . 7 mev electronic radiation , the response tune , fall time of trailing edge , full width of half maximum ( fwhm ) , sensitivity , carrier life , mobility are researched and contrasted . the result shows that the response speed of detector , time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation . though sensitivity of the detector reduces , its measuring range can be widened
为了使探测器的性能得到进一步的提高，我们对其进行了电子辐照改性，并测量了本征砷化镓探测器和经过1 . 7mev电子辐照的探测器的暗电流、光电流及对x射线的脉冲响应，并对其响应时间，后沿下降时间，半高宽( fwhm ) ，载流子寿命，灵敏度进行对比，研究，结果显示经电子辐照后的探测器的性能得到了改善，使响应速度，分辩率进一步提高，并消除了探测器输出信号后沿的非线性，虽灵敏度有所降低，反而使其测量范围得以拓宽。
