Scientific Achievement
Developed room-temperature (20C) and low-temperature (80C) solution synthesis procedures for a new class of metal-halide perovskite high entropy semiconductor (HES) single crystals.
Significance and Impact
The achievement of any high entropy material, especially in a single crystal form, at room-temperature or at low-temperature (80C) is unprecedented and enables the rational design of other novel high entropy systems with low cohesive energies.
Research Details
- Synthesis of two families of single crystalline 5- and 6-element high entropy perovskite semiconductors
- Confirmation of near-equimolar ratios of 5 and 6 different octahedra disordered within a single crystal
- Energy transfer between the octahedra within a single crystal, allowing for golden emission
