Application

In the form of single or few-layer thin films,?exfoliated SnS?nanosheets have various applications.?These include light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric and photovoltaic devices.
Bandgap 1.07 -1.32 eV
Chemical Synthesis

Tin sulfide?(SnS)?is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.
color  Brown/Yellow
Description Tin sulfide (SnS), with a direct energy band-gap of about 1.3 eV, and a high optical absorption coefficient over 5 × 104 cm-1,?is a promising new candidate for applications in the next generation of photovoltaic solar cells. Made of earth-abundant, relatively cheap and environmentally-nontoxic elements, SnS is solution processable and stable in both alkaline and acidic conditions.
Electronic properties 2D semiconductor
Preparation Synthetic?- Chemical Vapour Transport (CVT)
Usage 

Tin sulfide single crystals?can be used to prepare monolayer and few-layer SnS?by mechanical or liquid exfoliation.
