Multiple scattering in grazing-incidence X-ray diffraction: Impact on lattice-constant determination in thin films

Dynamical scattering effects are observed in grazing-incidence X-ray diffraction experiments using an organic thin film of 2,2′:6′,2′′-ternaphthalene grown on oxidized silicon as substrate. Here, a splitting of all Bragg peaks in the out-of-plane direction (z-direction) has been observed, the magnitude of which depends both on the incidence...

The Epitaxial Growth of Self-Assembled Ternaphthalene Fibers on Muscovite Mica

The morphology and structure of 2,2':6',2?-ternaphthalene (NNN) deposited on muscovite mica(001) substrates was investigated by scanning force microscopy (SFM) and specular X-ray diffraction measurements. Consistently, both methods reveal the coexistence of needle-like structures with a {111} contact plane and {001} orientated island-like...
