Abstract
Recently, two new members of layered transition metal dichalcogenides, rhenium disulfide and diselenide (ReS2/ReSe2) have been successfully synthesized in laboratory and rapidly attracted researchers’ interests for their distinctive properties. Compared to the conventional molybdenum- or tungsten-based transition metal dichalcogenides, rhenium disulfide and diselenide exhibit significant differences. Essentially, the stable structure of ReS2/ReSe2 is distorted 1-T’ phase rather than 2-H phase with high symmetry. The low-symmetric structure will lead to unique optical and electric properties, for instance, ferroelectricity. A review of research on ReS2/ReSe2 will be given in this talk as well as the proposed experimental methodology to measure the potential ferroelectricity in layered ReS2/ReSe2 materials.
