    • Carrier-density control of the SrTiO3 (001) surface 2DEG studied by ARPES 

      McKeown Walker, Siobhan Ellen; Bruno, Flavio Y; Wang, Zhiming; de la Torre, Alberto; Riccó, Sara; Tamai, Anna; Kim, Timur; Hoesch, Moritz; Shi, Ming; Bahramy, Mohammed Saeed; King, Phil; Baumberger, Felix (2015) - Journal article
      The origin of the 2D electron gas (2DEG)stabilized at the bare surface of SrTiO3 (001) is investigated. Using high-resolution angle-resolved photoemission and core-level spectroscopy, it is shown conclusively that this ...
    • Effects of spin-orbit coupling and many-body interactions on the electronic structure of Sr₂RuO₄ 

      Rozbicki, Emil Jerzy (University of St Andrews, 2011-11-30) - Thesis
      The aim of the project is to investigate the effects of spin-orbit coupling and many-body interactions on the band structure of the single-layered strontium ruthenate Sr₂RuO₄. This material belongs to the large family ...
    • The electronic structure of the nematic materials Sr₃Ru₂O₇ and Ca(Co[subscript(x)]Fe[subscript(1-x)])₂As₂ 

      Allan, Milan P. (University of St Andrews, 2010-11-22) - Thesis
      We investigated the electronic structure of the two nematic materials Sr₃Ru₂O₇ and Ca(Fe₀.₉₇Co₀.₀₃As)₂ using spectroscopic – imaging scanning tunneling microscopy (SI-STM) and angle resolved photoemission spectroscopy ...
    • Formation of heavy d-electron quasiparticles in Sr3Ru2O7 

      Allan, Milan Peter; Tamai, Anna; Rozbicki, Emil Jerzy; Fischer, M. H.; Voss, J.; King, Phil; Meevasana, Worawat; Thirupathaiah, S.; Rienks, E.; Fink, J.; Tennant, David Alan; Perry, Robin Stuart; Mercure, Jean-Francois; Wang, M. A.; Lee, Jinho; Fennie, C. J.; Kim, E-A; Lawler, M. J.; Shen, K. M.; Mackenzie, Andrew; Shen, Z-X; Baumberger, Felix (2013-06-20) - Journal article
      The phase diagram of Sr3Ru2O7 shows hallmarks of strong electron correlations despite the modest Coulomb interaction in the Ru 4d shell. We use angle-resolved photoelectron spectroscopy measurements to provide microscopic ...
    • Large tunable Rashba spin splitting of a two-dimensional electron gas in Bi2Se3 

      King, Phil; Hatch, R. C.; Bianchi, M.; Ovsyannikov, R.; Lupulescu, C.; Landolt, G.; Slomski, B.; Dil, J. H.; Guan, D.; Mi, J. L.; Rienks, E. D. L.; Fink, J.; Lindblad, A.; Svensson, S.; Bao, S.; Balakrishnan, G.; Iversen, B. B.; Osterwalder, J.; Eberhardt, W.; Baumberger, Felix; Hofmann, Ph. (2011-08-25) - Journal article
      We report a Rashba spin splitting of a two-dimensional electron gas in the topological insulator Bi2Se3 from angle-resolved photoemission spectroscopy. We further demonstrate its electrostatic control, and show that spin ...
    • Spectroscopic indications of polaronic behavior of the strong spin-orbit insulator Sr3Ir2O7 

      King, Phil; Takayama, T.; Tamai, Anna; Rozbicki, Emil Jerzy; McKeown Walker, Siobhan Ellen; Shi, M.; Patthey, L.; Moore, R.G.; Lu, D.; Shen, K. M.; Takagi, H.; Baumberger, Felix (2013-06-24) - Journal article
      We investigate the bilayer Ruddlesden-Popper iridate Sr3Ir2O7 by temperature-dependent angle-resolved photoemission. At low temperatures, we find a fully gapped correlated insulator, characterized by a small charge gap and ...
