Metal-insulator transition in SrTiO(3-x) thin films induced by frozen-out carriers.
The metal-insulator transition (MIT) observed in the SrTiO(3-x) film was found to be induced by the carrier freeze-out effect and its electrical properties were found that O(vac) in bulk SrTi olefins is far from uniform over the whole material.
Thin films of the spin ice compound Ho2Ti2O7
The pyrochlore compounds Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7 show an exotic form of magnetism called the spin ice state, resulting from the interplay between geometrical frustration and ferromagnetic
Imaging and control of ferromagnetism in LaMnO3/SrTiO3 heterostructures
An atomically sharp transition to a ferromagnetic phase when polar antiferromagnetic LaMnO3 (001) films are grown on SrTiO3 substrates is reported, demonstrating that functionalities can be engineered in oxide films that are only a few atomic layers thick.

Magnetotransport and induced superconductivity in Bi based three‐dimensional topological insulators
The surface of a three-dimensional (3D) topological insulator is conducting and the topologically nontrivial nature of the surface states is observed in experiments. It is the aim of this paper to
Geometric dependence of Nb-Bi2Te3-Nb topological Josephson junction transport parameters
Part of Special issue on Topological Superconductors Superconductor-topological insulator–superconductor Josephson junctions have been fabricated in order to study the width dependence of the
Reversible metal-insulator transition in LaAlO 3 thin films mediated by intragap defects: An alternative mechanism for resistive switching
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 electrically inert
Rayleigh-instability-driven simultaneous morphological and compositional transformation from Co nanowires to CoO octahedra
Arrays of regularly distributed CoO nano-octahedra are obtained by annealing Co nanowires at high temperatures. Both the size and the separation distance of the nano-octahedra can be controlled by
Effect of high oxygen pressure annealing on superconducting Nd1.85Ce0.15CuO4 thin films by pulsed laser deposition from Cu-enriched targets
We show that the quality of Nd1.85Ce0.15CuO4 films grown by pulsed laser deposition can be enhanced by using a non-stoichiometric target with extra copper added to suppress the formation of a
