Fig. 1. Characterizations of vdW multiferroic CCPS single crystal.

Fig. 1

a The side-view (interlayer bc-plane) and b the top-view (intralayer ab-plane) of CCPS atomic structure, Cu, Cr, P, and S ions are represented by green, blue, red, and yellow balls, respectively. c The XRD scan indicating (002), (004), and (008) peak reflections for the ab-plane of as-grown CCPS single crystal. The inset shows a photo of the crystal bulk. d High-resolution TEM image of the ab-plane confirming good single crystalline, with scale-up capture in the inset. e The simulated and f the measured electron diffraction image of monoclinic CCPS structure along the c axis, showing high consistency. The hexagonal patterns connected by dotted red lines in (e) and (f) correspond to the one connected by dotted black lines in (b).
