Interplay of ballistic and chemical effects in the formation of structural defects for Sn and Pb implanted silica
R. J. Green, A. Hunt, D. A. Zatsepin +6
The electronic structures of Sn and Pb implanted SiO2 are studied using soft X-ray absorption (XAS) and emission (XES) spectroscopy. We show, using reference compounds and ab initi…
X-ray spectra and electronic structure of FeAs superconductors
E. Z. Kurmaev, R. G. Wilks, A. Moewes +5
The densities of the valence and conduction band electronic states of the newly discovered layered superconductors LaOFeAs, LaOFFeAs (Tc=26 K), SmOF$_{0.…
Effect of 3d-doping on the electronic structure of BaFe2As2
J. A. McLeod, A. Buling, R. J. Green +10
The electronic structure of BaFe2As2 doped with Co, Ni, and Cu has been studied by a variety of experimental and theoretical methods, but a clear picture of the dopant 3d states ha…
Electronic band gap reduction and intense luminescence in Co and Mn ion-implanted SiO
R. J. Green, D. A. Zatsepin, D. J. St. Onge +4
Cobalt and manganese ions are implanted into SiO over a wide range of concentrations. For low concentrations, the Co atoms occupy interstitial locations, coordinated with oxyge…
Identifying structural order in Selenium with Near-Edge Spectroscopy
J. A. McLeod, N. Chen, R. E. Johanson +4
We investigate the crystallization of amorphous arsenic-selenium alloys with 0%, 0.5%, 2%, 6%, 10%, and 19% arsenic by atomic concentration using synchrotron X-ray absorption spect…
Fundamental Crystal Field Excitations in Magnetic Semiconductor SnO:Mn,Fe,Co,Ni
B. Leedahl, D. J. McCloskey, D. W. Boukhvalov +7
Directly measuring elementary electronic excitations in dopant metals is essential to understanding how they function as part of their host material. Through calculated crysta…
