Depth-dependent ordering, two-length-scale phenomena and crossover behavior in a crystal featuring a skin-layer with defects
Charo I. Del Genio, Kevin E. Bassler, Aleksandr L. Korzhenevskii +4
Structural defects in a crystal are responsible for the "two length-scale" behavior, in which a sharp central peak is superimposed over a broad peak in critical diffuse X-ray scatt…
Effect of Strain on the Growth of InAs/GaSb Superlattices: An X-Ray Study
J. H. Li, D. W. Stokes, J. C. Wickett +3
We present a detailed x-ray diffraction study of the strain in InAs/GaSb superlattices grown by molecular beam epitaxy. The superlattices were grown with either InSb or GaAs interf…
Depth-dependent critical behavior in V2H
Charo I. Del Genio, Johann Trenkler, Kevin E. Bassler +5
Using X-ray diffuse scattering, we investigate the critical behavior of an order-disorder phase transition in a defective "skin-layer" of V2H. In the skin-layer, there exist walls…
Fermi-surface induced modulation in an optimally doped YBCO superconductor
Xuerong Liu, Zahirul Islam, Sunil K. Sinha +4
We have observed a Fermi-surface (FS) induced lattice modulation in a YBCO superconductor with a wavevector along CuO chains, {\it i.e.} =(0,,0). The value of $δ\sim0…
A 4-unit-cell superstructure in optimally doped YBa2Cu3O6.92 superconductor
Zahirul Islam, X. Liu, S. K. Sinha +8
Using high-energy diffraction we show that a 4-unit-cell superstructure, q0=(1/4,0,0), along the shorter Cu-Cu bonds coexists with superconductivity in optimally doped YBCO. A comp…
