Tin(II) Sulfide (SnS) Crystal CAS 1314-95-0

Tin(II) sulfide crystal, high purity semiconducting material

For applications in next generation photovoltaic solar cells

Tin(II) sulfide (SnS), CAS number 1314-95-0, 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.

Like the other family members of layered group IV monochalcogenides (including SnSe, GeS, and GeSe), 2D layered SnS has puckered structures - similar to those of black phosphorus. SnS crystallises in the form of an orthorhombic structure, where each Sn(II) atom is coordinated to six S atoms - with three short Sn–S bonds within the surface and three longer Sn-S bonds connecting outer surface of the same layer.

As an analogue to phosphorene, 2D SnS has also been predicted to have strong in-plane anisotropy. However, with two elements of different electronegativity (compared to phosphorene with its single element), the symmetry of SnS structure is rendered, leading to even richer physical properties.

Viscoelastic Transfer of 2D Material Using PDMS

Viscoelastic transfer using polydimethylsiloxane (PDMS) stamps is one of the methods used for the deterministic placement of 2D materials and the fabrication of van der Waals heterostructures. It relies on the viscoelasticity of PDMS, which behaves as an elastic solid on short time scales, but as a viscous fluid on long time scales.
