Multivariate image analysis methods applied to XPS imaging data sets
Recent improvements in imaging photoelectron spectroscopy enhance lateral and vertical characterization of heterogeneous samples at the cost of increasing complexity in the XPS data sets acquired. These imaging data sets require more sophisticated analysis methods than visual inspection if the data are to be interpreted effectively. Multivariate analysis (MVA) methods are increasingly utilized ...
متن کاملA Data Focusing method for Microwave Imaging of Extended Targets
This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...
متن کاملGetting more from XPS imaging: multivariate analysis for spectromicroscopy
The spherical mirror analyser (SMA) is used to acquire fast XPS images from specimen surfaces with high lateral and energy resolution. Here we review the properties of the SMA including spatial and energy resolution and provide examples of the capabilities of such an imaging analyser. In the last few years the combination of the SMA with a two-dimensional, pulse counting electron detector has a...
متن کاملAspects of using the factor analysis for XPS data interpretation
In this work, the use of factor analysis to chemical state quantification of XPS data is studied. First, the theory of the method is reviewed with a special emphasis on the issues related to XPS data analysis. In particular, we concentrate on the transformation of the abstract components into physically meaningful ones in the case where reliable reference spectra are not available. We have obse...
متن کاملA Review of XPS Data-Banks
Information derived or interpreted from analyses of X-ray Photoelectron Spectroscopy (XPS) data is frequently used to make valuable decisions in business, product development, process improvement and materials characterization. For this reason, it is important to understand the characteristics of the reference data stored in the data-banks that are currently used to obtain this information. Thi...
