Rich diversity of crystallographic phase formation in 2D Re_xMo_(1-x)S_2(x< 0.5) alloy

摘要

We report on the observation of the rich variety of crystallographic phase formation in a RexMo1-xS2 alloy for x 0.5. For x 0.23, no low dimensional superstructural modulation is observed and inter cation hybridization remains discrete, forming dimers to tetramers with increasing Re concentration. 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. Published under license by AIP Publishing.
