Quantitative Electron Probe Microanalysis of Rough, Bulk Samples

Abstract
Surface roughness degrades the accuracy of quantitative electron probe x-ray microanalysis through the action of geometric effects on x-ray production and absorption. Measurements of rough surfaces produced on NIST microhomogeneous SRMs will be used to address key questions on the phenomenon: (1) What is the magnitude of the roughness (geometrical) effect? (2) What is its dependence on photon energy? (3) Can overscanning a rough area, assuming it is locally homogeneous in composition, compensate for roughness? (4) Can the peak-to-local-background ratio be used to compensate for roughness effects in point analyses?Citation
