Claims6
A high-entropy alloy composition comprising at least four different transition metals from groups V and VI of the periodic table alloyed on a cation sublattice, wherein:
- a. the composition comprises a two-dimensional (2D) high-entropy transition metal dichalcogenide (TMDC) comprising one of (M(1)M(2)M(3)M(4))0.25X2, and (M(1)M(2)M(3)M(4)M(5))0.20X2, wherein M(1), M(2), M(3), M(4), and M(5) are independently selected from the group consisting of V, Nb, Ta, Mo, and W, and X is selected from the group consisting of S and Se;
- and
- b. individual elements of the at least four different transition metals and the cation sublattice are randomly distributed throughout a 3D structure of the composition.
