TLDR
The modelling of grazing-incidence small-angle X-ray scattering (GISAXS) from three-dimensional quantum dot lattices is described.Abstract:
The ordering of quantum dots in three-dimensional quantum dot lattices is investigated by grazing-incidence small-angle X-ray scattering (GISAXS). Theoretical models describing GISAXS intensity distributions for three general classes of lattices of quantum dots are proposed. The classes differ in the type of disorder of the positions of the quantum dots. The models enable full structure determination, including lattice type, lattice parameters, the type and degree of disorder in the quantum dot positions and the distributions of the quantum dot sizes. Applications of the developed models are demonstrated using experimentally measured data from several types of quantum dot lattices formed by a self-assembly process.read more

Small Angle X-ray Scattering for Nanoparticle Research
TL;DR: This work provides a theoretical foundation for X-ray scattering, considering both form factor and structure factor, as well as the use of correlation functions, which may be used to determine a particle's size, size distribution, shape, and organization into hierarchical structures.

Advanced grazing-incidence techniques for modern soft-matter materials analysis.
TL;DR: Advanced grazing-incidence techniques have developed significantly and novel methods have emerged which allow for an in-depth morphology characterization of modern soft-matter materials, including the potential to investigate polarization.
High-resolution X-ray scattering
TL;DR: In this article, the beamline and spectrometer instrumentation for high-resolution X-ray scattering at the Stanford Synchrotron Radiation Laboratory is described, and the combination of photon intensity at the sample of ∼ 1013 photons/s 10 mm2 and the momentum transfer resolution of ΔQ ∼ 10 −4 A −1 make this a unique facility.
