We present an X-ray diffraction study of a semiconductor symmetric tilt grain boundary. The theory of crystal truncation rod scattering is extended to bicrystal interfaces and compared with experimental data measured at the Diamond Light Source.

Average Structure

X-ray precession technique1 has been utilized to study the reciprocal space of the superconducting single crystal Bi 2 Sr 2 CaCu 2 O y. An average structure with space group of Pnnn and a real structure with the superspace group of [Formula: see text] or [Formula: see text] have been found for this one dimensional modulated incommensurate material. As well, a basic structure with the space group of Fmmm is derived from the experimental data.

Single Crystal Analysis

Abstract X-ray single crystal analysis of MnSO4·5H2O shows that the manganese atoms are octahedrally coordinated by oxygen atoms, four of which belong to water molecules and two to sulphate groups. A model derived from the crystal structure was fitted to the X-ray scattering intensities from aqueous MnSO4. Good agreement with experimental data is achieved using a model in which Mn(H2O)6-z(OSO3)z+2-2z interacts with about ten water molecules and each sulphate ion with about seven water molecules.

Crystal Truncation Rod

We present a method of modelling the X-ray diffraction (XRD) from buried quantum dots (QDs). Both diffuse scattering and crystal truncation rods can be modelled by calculating the scattering atomistically and adding a contribution from the bulk crystal. Because there are a large number of atoms, their positions cannot be fitted independently and Keating energy minimisation is used to ensure that the strain is physically realistic. Calculated scattering is compared with experimental data, and some of the challenges presented by real QDs are considered.
