Two-dimensional superconductor-insulator quantum phase transitions in an electron-doped cuprate
S. W. Zeng, Z. Huang, W. M. Lv +12
We use ionic liquid-assisted electric field effect to tune the carrier density in an electron-doped cuprate ultrathin film and cause a two-dimensional superconductor-insulator tran…
Metallic state in La-doped YBaCuO thin films with -type charge carriers
S. W. Zeng, X. Wang, W. M. Lü +10
We report hole and electron doping in La-doped YBaCuO(YBCO) thin films synthesized by pulsed laser deposition technique and subsequent \emph{in-situ} postannealing in o…
Reversible metal-insulator transition in LaAlO3 thin films mediated by intragap defects: An alternative mechanism for resistive switching
Z. Q. Liu, D. P. Leusink, W. M. Lü +13
We report on the electric-field-induced reversible metal-insulator transition (MIT) of the insulating LaAlO3 thin films observed in metal/LaAlO3/Nb-SrTiO3 heterostructures. The swi…
Nonlinear Insulator in Complex Oxides
Z. Q. Liu, D. P. Leusink, W. M. Lü +10
The insulating state is one of the most basic electronic phases in condensed matter. This state is characterised by an energy gap for electronic excitations that makes an insulator…
