| Abstract Scope |
High entropy materials offer vast and unexplored compositional phase spaces not accessible in traditional binary and ternary systems. Stabilization of single crystals comprised of 5 or more elements in increasingly complex and reduced symmetry crystal structures is providing new opportunities for discovery of unexpected exotic behaviors. Recent examples have shown that these systems can possessing unique combinations of structural, thermal, and chemical robustness in combination with continuously controllable electronic, magnetic, and optical properties suitable to advanced computing and sensing architectures. The extraordinarily short quench times associated with laser ablation are perfectly suited to stabilizing these materials in ideal randomly mixed solid solutions. We will discuss our ongoing work using non-equilibrium pulsed laser deposition to synthesize perovskite, spinel, and Ruddlesden-Popper single crystal high entropy oxides. A range of observed functionalities will be described through fundamental many body effects driven by inherent frustrations in the underlying spin, charge, and lattice order parameters. |
