Maximizing solubility in rock salt high-entropy oxides
Matthew Furst, Joseph Petruska, Dhiya Srikanth +5
To explore and quantitatively map the cation-size mismatch solubility limits in high-entropy oxides (HEOs), we report on Ca substitution in prototypical MgCoNiCuZnO, because…
Thermodynamics-Inspired High-Entropy Oxide Synthesis
Saeed S. I. Almishal, Matthew Furst, Yueze Tan +8
High-entropy oxide (HEO) thermodynamics transcend temperature-centric approaches, spanning a multidimensional landscape where oxygen chemical potential plays a decisive role. Here,…
Performance of Exchange-Correlation Approximations to Density-Functional Theory for Rare-earth Oxides
Mary Kathleen Caucci, Jacob T. Sivak, Saeed S. I. Almishal +4
Rare-earth oxides (REOs) are an important class of materials owing to their unique properties, including high ionic conductivities, large dielectric constants, and elevated melting…
Discovering High-Entropy Oxides with a Machine-Learning Interatomic Potential
Jacob T. Sivak, Saeed S. I. Almishal, Mary K. Caucci +7
High-entropy materials shift the traditional materials discovery paradigm to one that leverages disorder, enabling access to unique chemistries unreachable through enthalpy alone.…
Local structure maturation in high entropy oxide (Mg,Co,Ni,Cu,Zn)1-x(Cr,Mn)xO thin films
Gabriela E. Niculescu, Gerald R. Bejger, John P. Barber +8
High entropy oxides (HEO)s have garnered much interest due to their available high degree of tunability. Here, we study the local structure of (MgNiCuCoZn)0.167(MnCr)0.083O, a comp…
Untangling individual cation roles in rock salt high-entropy oxides
Saeed S. I. Almishal, Jacob T. Sivak, George N. Kotsonis +10
We unravel the distinct roles each cation plays in phase evolution, stability, and properties within Mg1/5Co1/5Ni1/5Cu1/5Zn1/5O high-entropy oxide (HEO) by integrating experimental…
Order evolution from a high-entropy matrix: understanding and predicting paths to low temperature equilibrium
Saeed S. I. Almishal, Leixin Miao, Yueze Tan +9
Interest in high-entropy inorganic compounds originates from their ability to stabilize cations and anions in local environments that rarely occur at standard temperature and press…
On the thermal and mechanical properties of MgCoNiCuZnO across the high-entropy to entropy-stabilized transition
Christina M. Rost, Daniel L. Schmuckler, Clifton Bumgardner +7
As various property studies continue to emerge on high entropy and entropy-stabilized ceramics, we seek further understanding of property changes across the phase boundary between…
What is in a Name: Defining -High Entropy- Oxides
Matthew Brahlek, Maria Gazda, Veerle Keppens +10
High entropy oxides are emerging as an exciting new avenue to design highly tailored functional behaviors that have no traditional counterparts. Study and application of these mate…
High-entropy ceramics: propelling applications through disorder
Cormac Toher, Corey Oses, Marco Esters +6
Disorder enhances desired properties, as well as creating new avenues for synthesizing materials. For instance, hardness and yield stress are improved by solid-solution strengtheni…
Searching for Superconductivity in High Entropy Oxide Ruddlesden-Popper Cuprate Films
Alessandro R. Mazza, Xingyao Gao, Daniel J. Rossi +10
In this work, the high entropy oxide A2CuO4 Ruddlesden-Popper (La0.2Pr0.2Nd0.2Sm0.2Eu0.2)2CuO4 is explored by charge doping with Ce+4 and Sr+2 at concentrations known to induce sup…
