论文摘要
In previous work a different and powerful, analytical, technique was used to get data, such as the absolute atom concentration (AAC), specimen thickness etc., from public domain boron nitride EELS spectrum collected under a collection semi-angle, $β$, less than the plasmon cutoff angle, $θ_{c}$, but large relative to incident beam convergence, $α$.在这里,寻求某种完整性,另一种数值,技术可用,也可以用$β<θ_{c} $进行分钟细节描述,并应用于使用$β/α<2 $获得的数据,因此需要与事件相关相关的相关校正。许多实验性物理参数彼此完全相关均来自单个鳗鱼谱。公共域硝酸盐硅,si $ _ {3} $ n $ _ {4} $,使用的鳗鱼光谱。由两个$β<θ_{C} $ - 与之相关的技术可产生的结果之间的比较。结果范围从AAC,密度,等离子临界载体,等离子体分散系数,费米能等参数到标本厚度。使用EELSMICR程序的5版获得了结果,并将其与使用非EELS技术获得的现有结果进行了比较。
In previous work a different and powerful, analytical, technique was used to get data, such as the absolute atom concentration (AAC), specimen thickness etc., from public domain boron nitride EELS spectrum collected under a collection semi-angle, $β$, less than the plasmon cutoff angle, $θ_{c}$, but large relative to incident beam convergence, $α$. Here, seeking for some completeness, another, numerical, technique usable together with, also, $β< θ_{c}$ is described in minute detail and applied to data obtained with $β/α< 2$, so necessitating incident beam convergence-related corrections. A lot of experimental physical parameters all fully relevant to one another are produced from a single EELS spectrum. Of public domain silicon nitride, Si$_{3}$N$_{4}$, EELS spectrum used. Comparison between results producible by the two $β<θ_{c}$-related techniques made. Results range from parameters such as AAC, density, plasmon critical vector, plasmon dispersion coefficient, Fermi energy to specimen thickness. Results were obtained using version 5 of eelsMicr program and compared with existing results obtained using non EELS techniques.
