Abstract

The analysis of the structures and microstructures of nanostructured thin layers can be performed using laboratory grazing incidence diffraction, provided accurate corrections are performed to handle the instrumental broadening effects related to the experiment geometry for an impinging beam close to the critical angle. Implementing these corrections in Rietveld refinement software allows the accurate extraction of quantitative relevant information about the structure (strain and atomic positions) and the microstructure (crystallite size and microstrain), selectively probing the material on a depth of few nanometers.

2. For instance, size quantization effects may occur in semiconducting nanoparticles, where it might interesting to match the particle size and the exciton diameter and/or tune the energy gap between the valence and the conduction band to produce a blue shift in the optical absorption. In magnetic or ferroelectric nanocrystals, the particle size of the oxide can be reduced to critically match that of a single ferro domain in which the magnetic or dipole moments are aligned: the magnetization or the polarization is then no longer nonlinear in the presence of an applied field and hysteresis loops disappear.Google Scholar

11. When α << αc the two waves get out of phase and the evanescent wave vanishes. For α >> αc the reflected wave amplitude vanishes and the evanescent wave amplitude then matches the incident wave. Finite absorption smears the kink at α = αc decreasing the amplification of the evanescent wave.>+αc+the+reflected+wave+amplitude+vanishes+and+the+evanescent+wave+amplitude+then+matches+the+incident+wave.+Finite+absorption+smears+the+kink+at+α+=+αc+decreasing+the+amplification+of+the+evanescent+wave.>Google Scholar
