On diffraction and absorption of X-rays in perfect crystals
Sergio L. Morelhao, Luis H. Avanci
This work reports the incompatibility of the Stokes relation for time reversibility of wave's propagation and the usage of complex atomic form-factor in diffraction theories. The i…
Strain field of InAs QDs on GaAs (001) substrate surface: characterization by synchrotron X-ray Renninger scanning
S. L. Morelhão, L. H. Avanci, R. Freitas +1
Precise lattice parameter measurements in single crystals are achievable, in principle, by X-ray multiple diffraction (MD) experiments. Tiny sample misalignments can compromise sys…
On the high accuracy lattice-parameters determination by n-beam diffraction: Theory and application to the InAs quantum dots grown over GaAs(001) substrate system
L. H. Avanci, A. A. Quivy, S. L. Morelhao +1
Ultra-precise lattice parameter measurements in single crystals are achievable, in principle, by X-ray multiple diffraction (XMD) experiments. Tiny sample misalignments have hinder…
Classical and quantum concepts of probability applied to diffraction physics in perfect crystals
Sérgio L. Morelhão, Luis H. Avanci
By following the trajectories of quantum particles inside a periodic lattice and preserving their classical probabilities for reflection, transmission and absorption at each lattic…
Automatic physical phasing X-ray crystallography
Sérgio L. Morelhão, Luis H. Avanci, Stefan Kycia
Phase invariants are important pieces of information about the atomic structures of crystals. There are several mathematical methods in X-ray crystallography to estimate phase inva…
