摘要
介绍了放射性同位素微电池的工作原理、选择GaN做为微电池能量转换材料的优势及同位素源选择的一些原则.为给GaN微电池找到一种合适的放射源,建立了Monte Carlo模拟计算模型.计算结果分析表明对于GaN放射性同位素微电池来说,最大能量为50 keV到100 keV区段的纯β放射体做源最为理想.
The working principle of radioisotope micro battery,the advantages of GaN for energy conversion materials in micro battery and the rules for isotope source selection are introduced in this paper.In order to select a suitable radioactive source for GaN micro battery,a simulation model of Monte Carlo is built.Analysis of the simulation results shows that pure β emitters with maximum energy from 50 keV to 100 keV range would be the best choice for GaN radioisotope micro battery.
