Combining non-specular X-ray scattering and X-ray absorption spectroscopy for the investigation of buried layers
The atomic structure and the chemical composition of buried interfaces is of high interest for many applications e.g. in multilayered samples such as oxidized metals, optic or microelectronic devices. Conventional surface analytical techniques such as X-ray photoelectron spectroscopy (XPS), Auger-electron spectroscopy (AES) or ion scattering spectroscopy (ISS) have an extremely high surface sen...
متن کاملX-ray and Raman scattering characterization of GelSi buried layers
The synthesis of semiconductor layered structures with abrupt interfaces is a major goal in the development of new materials with useful electrical and optical properties. Structures such as short-period superlattices, resonant tunneling diodes, and delta-doped layers can be improved by elimination of random potential fluctuations that tend to destroy coherent etfects such as tunneling, direct ...
متن کاملX-ray Absorption Spectroscopy
X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...
