  • Atomic-scale control of competing electronic phases in ultrathin LaNiO3 

    King, P. D. C.; Wei, H. I.; Nie, Y. F.; Uchida, M.; Adamo, C.; Zhu, S.; He, X.; Bozovic, I.; Schlom, D. G.; Shen, K. M. (2014-06) - Journal article
    In an effort to scale down electronic devices to atomic dimensions(1), the use of transition-metal oxides may provide advantages over conventional semiconductors. Their high carrier densities and short electronic length ...
  • Fluctuation-induced pair density wave in itinerant ferromagnets 

    Conduit, G. J.; Pedder, C. J.; Green, A. G. (2013-03-27) - Journal article
    Magnetic fluctuations near to quantum criticality can have profound effects. They lead to characteristic scaling at high temperature which may ultimately give way to a reconstruction of the phase diagram and the formation ...
  • Ultrafast adiabatic manipulation of slow light in a photonic crystal 

    Kampfrath, T.; Beggs, Daryl Matthew; White, Tom P; Melloni, A.; Krauss, Thomas Fraser; Kuipers, L. (2010-04-27) - Journal article
    We demonstrate by experiment and theory that a light pulse propagating through a Si-based photonic-crystal waveguide is adiabatically blueshifted when the refractive index of the Si is reduced on a femtosecond time scale. ...
  • Unusual Phase Behavior in the Piezoelectric Perovskite System, LixNa1-xNbO3 

    Peel, Martin; Ashbrook, Sharon Elizabeth Marie; Lightfoot, Philip (2013-08-05) - Journal article
    The system LixNa1-xNbO3has been studied by using a combination of X-ray and neutron powder diffraction and Na-23 solid-state NMR spectroscopy. For x = 0.05 we confirm a single polar orthorhombic phase. For 0.08 ≤ x ≤ 0.20 ...
