Comparison of silver and molybdenum microfocus X-ray sources for single crystal structure determination

L. Krause, R. Herbst-Irmer, G. M. Sheldrick and D. Stalke

Synopsis: A detailed comparison of single crystal diffraction data collected with Ag K[alpha] and Mo K[alpha] microsources (I[mu]S) indicates that the Ag K[alpha] data are better when absorption is significant. Empirical corrections intended to correct for absorption also correct well for the effects of the highly focused I[mu]S beams.

Sample tilt-free characterization of residual stress gradients in tin coatings using an in-plane arm-equipped laboratory X-ray diffractometer

A. Benediktovitch, T. Ulyanenkova, J. Keckes and A. Ulyanenkov

Synopsis: A methodology to use a laboratory X-ray diffractometer equipped with an in-plane arm to determine residual stress gradients is presented. The approach is based on an in-plane arm rotation and a characterization of several reflections to achieve a variation of X-ray penetration depth even without a sample inclination.

Crystallization behavior of diblock copolymers based on PCL and PLLA biopolymers

I. Navarro-Baena, A. Marcos-Fernandez, J. M. Kenny and L. Peponi

Synopsis: The crystalline structure and the melting/crystallization behavior of several synthesized diblock copolymers based on poly([epsilon]-caprolactone) (PCL) and poly(L-lactic acid) (PLLA) have been studied by differential calorimetry and X-ray diffraction analysis (small-angle X-ray scattering and wide-angle X-ray diffraction). The influence of the presence and of the molecular weight of each block on the crystallinity behavior and the crystal nature of the other block is discussed.

With a total exposure time of less than a minute, lattice tilts down to 10-4° could be distinguished locally on a focused-ion-beam-milled silicon wafer over a surface area of 100 × 100 µm.

Traceable GISAXS measurements for pitch determination of a 25 nm self-assembled polymer grating

Synopsis: The nominal pitch of 25 nm of a self-assembled block copolymer line grating was determined as 24.83 (9) nm by the first traceable grazing-incidence small-angle X-ray scattering measurements. Traceability is established by tracing all input parameters; the main contributions are the measurements of the sample-detector distance and of the pixel size.
