Although high-entropy materials are excellent candidates for a range of functional materials, their formation traditionally requires high-temperature synthetic procedures of over 1,000 °C and complex processing techniques such as hot rolling1–5. One
Here we develop room-temperature-solution (20°C) and low-temperature-solution (80°C) synthesis procedures for a new class of metal halide perovskite high-entropy semiconductor (HES) single crystals. Due to the soft, ionic lattice nature of metal halide perovskites, these HES single crystals ...
High-entropy materials (HEMs) hold promise for a variety of applications because their properties can be readily tailored by selecting specific elements and altering stoichiometry. In this Perspective, we highlight the emerging potential of HEMs in energy and electronic applications. We place particular...

To obtain further insight into the structural features of the high entropy A5MnSb2, structural refinement based on the single crystal XRD data was carried out. Due to the X-ray diffraction limits, the A site was treated as being singly occupied by Ba ions, which has a close number of elec...
We report on single-crystal growth of the equiatomic FeCoCrMnAl high-entropy alloy by means of the Bridgman technique. Our crystals are about 1cm in diameter and 6.6cm in length. X-ray Laue images taken at various positions on their surface are sharp and mutually consistent. The material has...
For the first time, a face-centered-cubic, single-crystal CoCrFeNiAl0.3 (designated as Al0.3), high-entropy alloy (HEA) was successfully synthesized by the Bridgman solidification (BS) method, at an extremely low withdrawal velocity through a constant temperature gradient, for which it underwent...
In recent years, the concept of entropy stabilization of crystal structures in oxide systems has led to an increased research activity in the field of "high entropy oxides". These compounds comprise the incorporation of multiple metal cations into single-phase crystal structures and interactions among...
Single-phase YYHEO was obtained due to its high entropy, but its crystal structure was highly disordered. Specifically, the cation sites were populated by five distinct cations with a large difference in ionic radius up to 50.9 %. The components contributed to the disorder of the crystal ...
X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), and electron backscatter diffraction (EBSD) collectively show the formation of a single high-entropy silicide phase. This high-entropy (Mo0.2Nb0.2Ta0.2Ti0.2W0.2)Si2 possesses a hexagonal C40 crystal structure with ABC stacking ...
