Fig. 3: Microstructures and crystallinity of the printed metal chalcogenides.
From: Generalised optical printing of photocurable metal chalcogenides
Scanning electron microscopy (SEM) images (left), X-ray diffraction (XRD) patterns (right), and photographs (inset) of the printed a Sb2S3, b Sb2Se3, c SnSe, d SnSe2, e Cu2S, and f SnS. The blue labels of the XRD patterns of panel c, d, and f indicate the peaks related to the crystalline orientation along c-axis of SnSe, a-axis of SnSe2, and c-axis of SnS, respectively. The black labels in the XRD pattern of panel d indicate the peaks other than the a-axis. Vertical blue lines indicate the patterns for the corresponding bulk references (Sb2S3: JCPDS 03-065-2434, Sb2Se3: JCPDS 01-083-7430, SnSe: JCPDS 00-032-1382, SnSe2: JCPDS 01-089-2939, Cu1.96S: JCPDS 00-012-0224, SnS: JCPDS 00-014-0620). SEM images (left) and Raman spectra (right) of g MoS2 and h PtS2. (Scale bars: SEM images: 3 μm, inset images: 5 mm) The labels in panels g and h indicate the Raman shift of the peaks in the spectrum.
