Synthesis of tin disulfide single crystals for nano‐layer exfoliation

Abstract

Efficient and inexpensive method of chemical transport based on Ag 2 S catalyst was used to produce relatively large crystals of SnS 2 , up to 5 mm in linear size. Good quality of the obtained layered crystals of SnS 2 was confirmed by X‐ray, SEM, EDX and Raman measurements, however the layers appeared to be slightly twisted in relation to each other. Nanometric (down to c.a. 10 nm) layers of SnS 2 on a Si substrate were obtained by mechanical exfoliation.
