Fig. 1: Structure evolution in NbSe2-xTex single crystals.
From: Self-assembly of 1T/1H superlattices in transition metal dichalcogenides
a Structures and morphologies of NbSe2-xTex single crystals with varying Te concentrations. b Crystal structures of different types of NbSe2-xTex single crystals: 2H, 1T/1H superlattice (6R), and distorted 1T (featuring a 1×3 reconstruction) types. The dashed lines indicates the unit cell. c X-ray diffraction (XRD) characterization of NbSe2-xTex single crystals with different Te concentrations. d Reduced lattice parameter (c/n) as a function of Te concentration (x). The solid black lines show the trends in the evolution of c/n with varying Te concentration.
