Highlighted illustration

Cover illustration: X-ray scattering diagrams of [W/Si]10 multilayers deposited at Ar pressures of 1, 3, 5 and 7 mTorr were measured at beamline BL16B1 at the Shanghai Synchrotron Radiation Facility (see Li, Zhu, Wang, Chen, Wang and Wang, pages 97-103). Larger scattering spots reveal rougher interfaces in multilayers grown at higher Ar pressure.

Synchrotron X-ray footprinting resources were investigated at a variety of beamlines and synchrotron facilities to understand their potential for a mobile general user. Results indicate that viable resources exist at each synchrotron investigated such that a prospective user need only provide a simple flow apparatus and sample handling accessories to perform this technique.

Grazing-incidence small-angle scattering patterns of Ge nanodots self-organized on Si(001) with soft X-rays showed a strongly anisotropic scattering profile, although the patterns with hard X-rays are symmetric. This apparent difference is explained in terms of the curvature of the Ewald sphere and anisotropic structure factors.
