GISAXS - Glancing incidence small angle X-ray scattering

Grazing-incidence small-angle X-ray scattering (GISAXS) on small periodic targets using large beams

Grazing-incidence small-angle X-ray scattering (GISAXS) is often used as a versatile tool for the contactless and destruction-free investigation of nano-structured surfaces. However, due to the shallow incidence angles, the footprint of the X-ray beam is significantly elongated, limiting GISAXS to samples with typical target lengths of several millimetres. For many potential applications, the p...

Characterization of Polymer Thin Films with Small-Angle X-ray Scattering under Grazing Incidence (GISAXS)

Polymer thin films have numerous technical applications as functional coatings, the most prominent example being PMMA coatings for lithography of integrated circuits and micromechanical devices. Polymer blends and block copolymers can be tailored for specific mechanical, optical, electric, and chemical properties. For instance, functional surfaces have been created by means of polymer blend and...

Structure of glancing incidence deposited TiO(2) thin films as revealed by grazing incidence small-angle X-ray scattering.

For the first time, grazing incidence small-angle X-ray scattering (GISAXS) analysis is used to characterize the morphology of TiO(2) thin films grown by glancing angle physical vapor deposition (GLAD). According to cross-section scanning electron microscopy (SEM) images, the films consist of near isotilted TiO(2) columns of different length and width depending on film thickness. The obtained G...

Application of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
