Abstract: Grazing incidence x-ray fluorescence (GIXRF) analysis technique has the potential of being one of the most powerful and versatile methods for characterization of layered materials, as it combines features of both x-ray reflectivity (XRR) and x-ray fluorescence techniques. GIXRF technique allows non-destructive evaluation of layer thickness, interface roughness, interlayer formation and depth profiling for an impurity element inside a layer medium or in the substrates. A computer program CATGIXRF, has been developed for GIXRF characterization of thin film and surfaces. Methodology of the program and its various features has been discussed in detail. The program offers analysis of GIXRF and XRR data simultaneously. The utility of the program has been demonstrated by example calculations and by providing a few examples of XRR and GIXRF characterization of a variety of thin-layered materials.
