Title: Experimental evidence for bipolaron condensation as a mechanism for the metal-insulator transition in rare-earth nickelates

Abstract

Many-body effects produce deviations from the predictions of conventional band theory in quantum materials, leading to strongly correlated phases with insulating or bad metallic behavior. One example is the rare-earth nickelates RNiO₃, which undergo metal-to-insulator transitions (MITs) whose origin is debated. Here, we combine total neutron scattering and broadband dielectric spectroscopy experiments to study and compare carrier dynamics and local crystal structure in LaNiO₃ and NdNiO₃. We find that the local crystal structure of both materials is distorted in the metallic phase, with slow, thermally activated carrier dynamics at high temperature. We further observe a sharp change in conductivity across the MIT in NdNiO₃, accompanied by slight differences in the carrier hopping time. Here, these results suggest that changes in carrier concentration drive the MIT through a polaronic mechanism, where the (bi)polaron liquid freezes into the insulating phase across the MIT temperature.

Tuning Bifunctional Oxygen Electrocatalysts by Changing the A-Site Rare-Earth Element in Perovskite Nickelates

Journal Article Wang, Le ; Stoerzinger, Kelsey A. ; Chang, Lei ; ... - Advanced Functional Materials

Perovskite-structured (ABO₃) transition metal oxides are promising bifunctional electrocatalysts for efficient oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). In this paper, we investigate a set of epitaxial rare earth nickelates (RNiO₃) thin films with controlled A-site isovalent substitution to correlate their structure and physical properties with ORR/OER activities. The ORR activity is shown to decrease monotonically with decreasing the A-site element ionic radius which lowers the conductivity of the RNiO₃ (R = La, La_0.5Nd_0.5, La_0.2Nd_0.8, Nd, Nd_0.5Sm_0.5, Sm, Gd) films, with LaNiO₃ being the most conductive and active. On the other hand, the OER activity initially increases uponmore »« less

Template Engineering of Metal-to-Insulator Transitions in Epitaxial Bilayer Nickelate Thin Films

Journal Article Lee, Jongmin ; Kim, Gi-Yeop ; Jeong, Seyeop ; ... - ACS Applied Materials and Interfaces

Understanding metal-to-insulator phase transitions in solids has been a keystone not only for discovering novel physical phenomena in condensed matter physics but also for achieving scientific breakthroughs in materials science. In this work, we demonstrate that the transport properties (i.e., resistivity and transition temperature) in the metal-to-insulator transitions of perovskite nickelates are tunable via the epitaxial heterojunctions of LaNiO₃ and NdNiO₃ thin films. Here, a mismatch in the oxygen coordination environment and interfacial octahedral coupling at the oxide heterointerface allows us to realize an exotic phase that is unattainable in the parent compound. With oxygen vacancy formation for strain accommodation,more »« less

Infrared reflectivity of the solid solutions LaNi{sub 1{minus}x}Fe{sub x}O{sub 3} (0.00{le}x{le}1.00)

Journal Article Massa, N E ; Falcon, H ; Salva, H ; ... - Physical Review, B: Condensed Matter

We report temperature-dependent far- and midinfrared reflectivity spectra of LaNi{sub (1{minus}x)}Fe{sub x}O{sub 3} solid solutions that span the passage from LaFeO{sub 3}, a room-temperature antiferromagnetic insulator, to LaNiO{sub 3}, a known metal oxide. Light Ni doping creates defects that induce extra bands assigned to electronic transitions within the insulating gap. An incipient Drude term emerges in the reflectivity spectrum of LaNi{sub 0.39}Fe{sub 0.61}O{sub 3} together with subbands that contribute to the electronic background. At these concentrations the dielectric response shows a picture in which the spectral weigh switches over toward far-infrared frequencies while phonon features develop strong antiresonances near longitudinal-opticalmore »« less

Low-temperature metallic behavior of amorphous MoO{sub 3}-TeO{sub 2} thin films

Journal Article Mukherjee, S ; Karmakar, S ; Sakata, H ; ... - Journal of Applied Physics

We report that vacuum-deposited amorphous MoO{sub 3}-TeO{sub 2} films of different thickness (469-1185 nm) and compositions show metal-insulator transition (MIT) in the temperature (T{sub p}) range 341-231 K (depending on thickness and composition). Interestingly, the corresponding thick bulk glass plates ({approx}0.2-0.5-mm thickness) of same compositions behave like the usual semiconducting transition metal oxide glasses over the entire range of temperature (80-400 K) and follow small polaron hopping (SPH) conduction mechanism. Temperature-dependent resistivity curves of the films showed peaks (maxima) around the respective MIT temperature T{sub p}, which shifted to the lower-temperature region with the increase of MoO{sub 3} content.

Polaron-induced metal-to-insulator transition in vanadium oxides from density functional theory calculations

Journal Article Kaur, Jasleen ; Chandrappa, Manas Likhit Holekevi ; Chen, Chi ; ... - Physical Review. B

Vanadium oxides have been extensively studied as phase-change memory units in artificial synapses for neuromorphic computing due to their metal-insulator transitions (MIT) at or near room temperature. Recently, injection of charge carriers into vanadium oxides, e.g., via optically via a heterostructure, has been proposed as an alternative switching mechanism and also potentially as a means to tune the MIT temperature. In this study, we explore the formation of small polarons in the low temperature (LT) insulating phases for V₃O₅,VO₂, and V₂O₃, and the barriers to their migration using density functional theory calculations. We find that V₃O₅ exhibits very low holemore »« less
