General Description
Tin disulfide (SnS2) is a member of the transition metal dichalcogenides (TMDCs) family. It has a layered structure, where each Sn ion coordinates to six S ions in a regular octahedron. Each sheet of Sn atoms is sandwiched between two sheets of S atoms, and each S-Sn-S layer is held by weak van de Vaals interactions. Like many other two dimensional semiconductors, SnS2 can undergo exfoliation to form atomic-layer sheets that have applications in FETs, photovolatic solar cells, sensors and photocatalyst applications.
SnS2 crystallises with a standard hexagonal crystal structure (2H-SnS2) which is identical to that of 1T-MoS2. Monolayers of 2H-SnS2 are stacked precisely on top of one another to form the 2H-polytype of bulk SnS2. It is noted that the 2H-SnS2 structure is different from that of 2H-MoS2, where the Mo atom possesses a trigonal prismatic coordination instead.
Applications
In the form of single or few-layer thin films, exfoliated tin disulfide nanosheets find applications ranging from light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric and photovoltaic devices.
Synthesis
Tin disulfide (SnS2) is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.
Usage
Tin disulfide single crystals can be used to prepare monolayer and few-layer SnS2 by mechanical or liquid exfoliation.
