Classification of 2D-GIWAXS Images of Highly Textured Molecular Thin Films Towards Indexation: Triclinic Lattices

Year: 2026

Type: article

Abstract: Low-symmetry triclinic lattices as formed by molecular thin films are conveniently characterized by grazing-incidence wide-angle x-ray scattering (GIWAXS). These films are often highly textured with a specific crystallographic plane HKL parallel to the surface and thus form uniaxial powders. A classification scheme is presented that lays the groundwork for determination of the surface lattice constants and indexing such complex scattering images. After identifying a first surface unit cell, methods are discussed for normalizing the lattice constants and further reduction of the unit cell.
