WebApr 14, 2024 · Unlike other chalcopyrite materials, the CuInS 2 prepared by electrodeposition exhibits similar or even higher performance than that of the CuInS 2 photoelectrodes prepared by co-evaporation or sputtering. Therefore, electrodeposition is a promising technique for synthesizing high-performance CuInS 2 thin films . WebNov 1, 2024 · Chalcopyrite is distributed in Sp2 with the “chalcopyrite disease” texture (Fig. 4 h). Meanwhile, galena is mostly euhedral to subhedral (size: 0.2–1.0 mm; Fig. 4 h), and some pyrrhotite replaced chalcopyrite locally (Fig. 4 j). Stage III is dominated by the calcite-sulfide assemblage, which occurs mainly as veins (2.0–5.0 cm wide).
