Demonstration of One-shot Spatially-resolved X-ray Absorption Spectroscopy Using Wavelength-dispersed Soft X-rays
2017
A one-shot recording technique for spatially-resolved X-ray absorption spectroscopy has been developed by combining wavelength-dispersed soft X-rays with a photoelectron emission microscope. The wavelength-dispersed soft X-rays, whose wavelength depends on the position, illuminate the sample, and a two-dimensional image of emitted electrons is obtained. Therefore, one can obtain spatial and spectroscopic information simultaneously, without scanning the monochromator. The technique opens the route to quantitative investigation for inhomogeneous and irreversible surface chemical reactions.
