Crystal mosaicity determined by a novel layer deconvolution Williamson–Hall method

Abstract

The application of conventional Williamson-Hall plot (WH) analysis to crystals often results in broadenings not proportional to the scattering length vector. Several reasons may influence the broadening such as composition...

Confronting Vegard’s rule in Ge1−x Sn x epilayers: from fundamentals to the effect of defects

“…Related to the former, it is first time the software is presented as final version to the scientific community. The latter, acronym for multiple reflection optimization package for XRD, in its single reflection mode has been often used for the simulation (and fitting) of the 2θ-ω scans using the dynamical theory of XRD [32][33][34][35][36][37][38] while the multiple reflection mode has been recently presented [38]. The code employs the dynamical theory of XRD and considers the effects of the instrumental function and the presence of Cu Kα 2 .…”

MROX 2.0: a software tool to explore quantum heterostructures by combining X-ray reflectivity and diffraction

“…The MROX code, as recognized software for the simulation of X-ray diffraction measurements, was used in X-ray diffraction single reflection mode. 53–58 The simulations considered pseudomorphic growth, i.e. , the Ge in-plane lattice parameter equals the ones from the Si substrate and Si buffer layer.…”

“…The MROX code, as recognized software for the simulation of X-ray diffraction measurements, was used in X-ray diffraction single reflection mode. [53][54][55][56][57][58] The simulations considered pseudomorphic growth, i.e., the Ge in-plane lattice parameter equals the ones from the Si substrate and Si buffer layer. Although the measured reflection is only sensitive in the orthogonal direction with respect to the surface, as it is only dependent on the c-lattice parameter, the calculated intensity is slightly affected by the volume of the unit cell which is different if the unit cell is relaxed or strained uniaxially.…”

Construction of type II ZnBi2O4/g-C3N4 heterojunction photocatalysts for efficient degradation of acid red B

“…The crystal size and strain were calculated using the Williamson–Hall method. The Williamson–Hall (W–H) equation is obtained using the following formula: 29 …”
