The influence of the specimen thickness on the core-edge loss intensity has been studied using the relative specimen thickness ( t R ) as the standard rule for the specimen thickness in EELS. The core-edge loss intensity monotonously increased with the increasing relative specimen thickness, 0 t R ⪷ 1, and monotonously decreased with increasing relative specimen thickness, t R ⪸ 1, behind the maximum of core-edge intensity at t R ≅ 1. “Optimum specimen thickness” to get the highest core-edge intensity is suggested for the thickness of t R = 1. The thickness-dependent factor T ( t R ) should be considered in a practical measurement in EELS. |
