First-order phase transition vs. spin-state quantum-critical scenarios in strain-tuned epitaxial cobaltite thin films
J. E. Dewey, V. Chaturvedi, T. A. Webb +12
Pr-containing perovskite cobaltites exhibit unusual valence transitions, coupled to coincident structural, spin-state, and metal-insulator transitions. Heteroepitaxial strain was r…
Crystal-Chemical Origins of the Ultrahigh Conductivity of Metallic Delafossites
Yi Zhang, Fred Tutt, Guy N. Evans +13
Despite their highly anisotropic complex-oxidic nature, certain delafossite compounds (e.g., PdCoO2, PtCoO2) are the most conductive oxides known, for reasons that remain poorly un…
Wide-range continuous tuning of the thermal conductivity of films via room-temperature ion-gel gating
Yingying Zhang, William M. Postiglione, Rui Xie +8
Solid-state control of the thermal conductivity of materials is of exceptional interest for novel devices such as thermal diodes and switches. Here, we demonstrate the ability to c…
Room-Temperature Valence Transition in a Strain-Tuned Perovskite Oxide
Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau +17
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very dif…
Soft X-ray Absorption Spectroscopy and Magnetic Circular Dichroism as Operando Probes of Complex Oxide Electrolyte Gate Transistors
Biqiong Yu, Guichuan Yu, Jeff Walter +5
Electrolyte-based transistors utilizing ionic liquids/gels have been highly successful in the study of charge-density-controlled phenomena, particularly in oxides. Experimental pro…
