Abstract:
Multiple-energy x-ray holography (MEXH) is a particular implementation of an x-ray holographic method capable of directly imaging atomic structures in the bulk, at surfaces and interfaces of solids. It utilizes an interference field generated by incident and scattered x-rays within the sample, then determines its strength at specific atomic sites from integral fluorescence yields. Scanning large portions of reciprocal space, a hologram is recorded, which can be converted to a real space image by Fourier transformation. Image aberrations that adversely affect results in single-energy techniques are successfully avoided in this novel multi-energy version.
