Exotic X-ray back-diffraction: a path toward a soft inelastic X-ray scattering spectrometer

Soft X-ray back-diffraction (XBD) is explored in an ultra-thin Si(220) crystal. Extreme XBD measurements show close agreement with theory, opening up new possibilities in X-ray optics.

Characterization of phase-transition-induced micro-domain structures in vanadium dioxide

All the possible kinds of phase-transition-induced domain structures in the insulating M1 and M2 phases of vanadium dioxide were theoretically predicted using a general space group method and characterized by transmission electron microscopy.
