Evolution of correlated electron behavior from the surface to the bulk in SrxCa1-xVO3

Autor: Ruimin Qiao, Ravi Pratap Singh, Johan Adell, Bo Chen, Jude Laverock, Joseph C. Woicik, Geetha Balakrishnan, Jithesh Kuyyalil, B. A. Karlin, Kevin E. Smith, Wanli Yang

Publikováno v: MRS Proceedings. 1730

We present a detailed depth-sensitive study of the evolution in correlated electron behavior from the surface of the prototypical correlated oxide, SrxCa1-xVO3, to its bulk. Photoemission measurements of varying surface sensitivity are employed to di

Response of chromium-doped alumina screens to soft x rays using synchrotron radiation

Autor: Uwe Arp, B. Zurro, B. A. Karlin, A. Baciero, K. J. McCarthy

Publikováno v: Journal of Applied Physics. 94:958-962

We have measured the response of chromium-doped alumina screens to soft x-ray radiation and derived quantum efficiency curves for the energy range from 2.5 to 4.5 keV. Persistent luminescence (or afterglow) from this material is observed for several

Resonant Raman scattering in potassium and chlorineKβx-ray emission from KCl

Autor: B. A. Karlin, P. L. Cowan, Stephen H. Southworth, K. E. Miyano, Y. | Ma

Publikováno v: Physical Review B. 54:12022-12028

We have measured the potassium {ital K}{sub {beta}} and chlorine {ital K}{sub {beta}} resonant Raman x-ray scattering from KCl. Strong {ital K}-shell absorption peaks are directly reflected in the resonant Raman spectra. The emission spectra are qual

Evolution of x-ray resonance Raman scattering into x-ray fluorescence from the excitation of xenon near theL3edge

Autor: Richard D. Deslattes, Albert Henins, Stephen H. Southworth, Yoshiro Azuma, P. L. Cowan, B. A. Karlin, M A MacDonald, Thomas W. LeBrun, J. C. Levin

Publikováno v: Physical Review A. 51:3598-3603

Near an absorption edge, x-ray emission cannot be treated separately from the absorption process itself; a scattering formalism must be used. Experimental data have been recorded showing x-ray emission from xenon following excitation by tunable synch

Publikováno v: Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films. 11:2354-2358

Triangulation from x‐ray standing wave applied to three Bragg planes, together with symmetry considerations, have established the geometrical structure of epitaxial Bi overlayers on GaAs (110). Our results are consistent with the epitaxial continue
