Title: Thickness-dependent metal-insulator transition in epitaxial SrRuO₃ ultrathin films

Abstract

Transport characteristics of ultrathin SrRuO₃ films, deposited epitaxially on TiO₂-terminated SrTiO₃ (001) single-crystal substrates, were studied as a function of film thickness. Evolution from a metallic to an insulating behavior is observed as the film thickness decreases from 20 to 4 unit cells. In films thicker than 4 unit cells, the transport behavior obeys the Drude low temperature conductivity with quantum corrections, which can be attributed to weak localization. Fitting the data with 2-dimensional localization model indicates that electron-phonon collisions are the main inelastic relaxation mechanism. In the film of 4 unit cells in thickness, the transport behavior follows variable range hopping model, indicating a strongly localized state. As a result, magnetoresistance measurements reveal a likely magnetic anisotropy with the magnetic easy axis along the out-of-plane direction.

Thickness-dependent metal-insulator transition in epitaxial SrRuO{sub 3} ultrathin films

Journal Article Shen, Xuan ; Center for Functional Nanomaterials, Brookhaven National Laboratory, Upton, New York 11973 ; Qiu, Xiangbiao ; ... - Journal of Applied Physics

Transport characteristics of ultrathin SrRuO{sub 3} films, deposited epitaxially on TiO{sub 2}-terminated SrTiO{sub 3} (001) single-crystal substrates, were studied as a function of film thickness. Evolution from a metallic to an insulating behavior is observed as the film thickness decreases from 20 to 4 unit cells. In films thicker than 4 unit cells, the transport behavior obeys the Drude low temperature conductivity with quantum corrections, which can be attributed to weak localization. Fitting the data with 2-dimensional localization model indicates that electron-phonon collisions are the main inelastic relaxation mechanism. In the film of 4 unit cells in thickness, the transportmore »« less

Origin of insulating and nonferromagnetic SrRuO₃ monolayers

Journal Article Ali, Zeeshan ; Wang, Zhen ; O’Hara, Andrew ; ... - Physical Review. B

The electro-magnetic properties of ultrathin epitaxial ruthenate films have long been the subject of debate. Here we combine experimental with theoretical investigations of (SrTiO₃)⁵-(SrRuO₃)ⁿ-(SrTiO₃)⁵ (STO⁵-SROⁿ-STO⁵) heterostructures with n = 1 and 2 unit cells, including extensive atomic-resolution scanning-transmission-electron-microscopy imaging, electron-energy-loss-spectroscopy chemical mapping, as well as transport and magneto-transport measurements. The experimental data demonstrate that the STO⁵-SRO²-STO⁵ heterostructure is nearly stoichiometric, metallic, and ferromagnetic with T_C ~ 128 K, even though it lacks the characteristic bulk-SRO octahedral tilts and matches the cubic STO structure. In contrast, the STO⁵-SRO¹-STO⁵ heterostructure features Ru-Ti intermixing in the RuO₂ layer, also without octahedral tilts, butmore »« less

Abrupt orthorhombic relaxation in compressively strained ultrathin SrRuO₃ films

Journal Article Siwakoti, Prahald ; Wang, Zhen ; Saghayezhian, Mohammad ; ... - Physical Review Materials

Lattice structure can dictate electronic and magnetic properties of a material. Especially, reconstruction at a surface or heterointerface can create properties that are fundamentally different from those of the corresponding bulk material. We have investigated the lattice structure on the surface and in the thin films of epitaxial SrRuO3 with the film thickness up to 22 pseudo-cubic unit cells (u.c.), using the combination of surface sensitive low energy electron diffraction and bulk sensitive scanning transmission electron microscopy. Our analysis indicates that, in contrast to many perovskite oxides, the RuO6 tilt and rotational distortions appear even in single unit cell SrRuO3more »« less

Metal-insulator transition in (111) SrRuO₃ ultrathin films

Journal Article Rastogi, Ankur ; Brahlek, Matthew ; Ok, Jong Mok ; ... - APL Materials

(111)-oriented transition metal oxide thin films provide a route to developing oxide-based topological quantum materials, but the epitaxial growth is challenging. Here, we present the thickness-dependent electronic and magnetic phase diagrams of coherently strained, phase pure (111)-oriented SrRuO₃ epitaxial films grown on (111) SrTiO₃ substrates using pulsed laser deposition. With decreasing film thickness, it is found that both the metal-to-insulator and magnetic phase transitions occur at the same thickness of 4–5 nm for films grown along both the (111) and the (001) directions. The character of the transport near the metal-insulator transition is, however, distinct for the different directions, whichmore »« less

Activation of ultrathin SrTiO₃ with subsurface SrRuO₃ for the oxygen evolution reaction

Journal Article Akbashev, A. R. ; Zhang, L. ; Mefford, J. T. ; ... - Energy & Environmental Science

Here, water electrolysis occurs via the oxygen/hydrogen evolution reactions. Achieving sufficiently high oxygen evolution reaction (OER) activity while maintaining stability of the active catalyst surface is a primary challenge of designing OER catalysts. Often high electrocatalytic activity is accompanied by structural instability. This is the case for the metallic perovskite oxide SrRuO₃ (SRO), which exhibits rapid dissolution under OER conditions, both as thin-films and as nanoparticles. On the other hand, large band-gap perovskite oxides such as SrTiO₃ (STO) are inactive for OER in the dark but are stable. In this work, we demonstrate that burying as little as one unitmore »« less
