  • Absence of giant spin splitting in the two-dimensional electron liquid at the surface of SrTiO3 (001) 

    McKeown Walker, S; Riccò, S; Bruno, F Y; de la Torre, A; Tamai, A; Golias, E; Varykhalov, A; Marchenko, D; Hoesch, M; Bahramy, M S; King, Philip David; Sánchez-Barriga, J; Baumberger, F (2016-06-22) - Journal article
    We reinvestigate the putative giant spin splitting at the surface of SrTiO3 reported by Santander-Syro et al. [Nature Mat. 13, 1085 (2014)]. Our spin- and angle-resolved photoemission experiments on fractured (001) oriented ...
  • Crossover from lattice to plasmonic polarons of a spin-polarised electron gas in ferromagnetic EuO 

    Riley, Jonathon Mark; Caruso, F; Verdi, C; Duffy, L; Watson, Matthew David; Bawden, Lewis; Volckaert, K; van der Laan, G; Hesjedal, T; Hoesch, M; Giustino, F; King, Philip David (2018-06-13) - Journal article
    Strong many-body interactions in solids yield a host of fascinating and potentially useful physical properties. Here, from angle-resolved photoemission experiments and ab-initio many-body calculations, we demonstrate how ...
  • Nearly-free-electron system of monolayer Na on the surface of single-crystal HfSe2 

    Eknapakul, T.; Fongkaew, I.; Vidyasagar, R.; Denlinger, J.D.; Bawden, Lewis; Mo, S.-K; King, Philip David; Takagi, H.; Limpijumnong, S.; Meesvasana, W. (2016-11-28) - Journal article
    The electronic structure of a single Na monolayer on the surface of single-crystal HfSe2 is investigate dusing angle-resolved photoemission spectroscopy. We find that this system exhibits analmost perfect “nearly-free-electron” ...
  • Spin-valley locking in the normal state of a transition-metal dichalcogenide superconductor 

    Bawden, Lewis; Cooil, S. P.; Riley, Jonathon Mark; Collins-McIntyre, Liam James; Sunko, Veronika; Hunvik, K.; Leandersson, M.; Polley, C. M.; Balasubramanian, T.; Kim, T. K.; Hoesch, M.; Wells, J. W.; Balakrishnan, G.; Bahramy, M. S.; King, Philip David (2016-05-23) - Journal article
    Metallic transition-metal dichalcogenides (TMDCs) are benchmark systems for studying and controlling intertwined electronic orders in solids, with superconductivity developing from a charge density-wave state. The interplay ...
  • Ultrafast band structure control of a two-dimensional heterostructure 

    Ulstrup, Søren; Grubišić Čabo, Antonija; Miwa, Jill A; Riley, Jonathon Mark; Grønborg, Signe S; Johannsen, Jens C; Cacho, Cephise; Alexander, Oliver; Chapman, Richard T; Springate, Emma; Bianchi, Mario; Dendzik, Maciej; Lauritsen, Jeppe V; King, Philip David; Hofmann, Philip (2016-06-28) - Journal article
    The electronic structure of two-dimensional (2D) semiconductors can be signicantly altered by screening effects, either from free charge carriers in the material itself, or by environmental screening from the surrounding ...
