Rich diversity of crystallographic phase formation in 2D RexMo1 – xS2 (x < 0.5) alloy

We report on the observation of the rich variety of crystallographic phase formation in a RexMo1 – xS2 alloy for x   0.23, superstructural modulation is observed. Depending on the Re concentrations (x = 0.23, 0.32, 0.38, and 0.45) and its distributions, various types of cation hybridization result in the rich variety of low dimensional superstructural modulation as directly revealed by high resolution transmission electron microscopy. These layered alloy systems may be useful for various energy and novel device applications.We report on the observation of the rich variety of crystallographic phase formation in a RexMo1 – xS2 alloy for x   0.23, superstructural modulation is observed.
