Molybdenum sulfide selenide (MoSSe), CAS number 132004-88-7, is a two-dimensional TMDC. It is often referred to as a "Janus" MXY transition metal dichalcogenide.

Janus MoSSe consists of three layers of atoms: Sulfur, molybdenum, and selenium from the top to the bottom in the sequence of S-Mo-Se. The geometry of monolayer Janus MoSSe is different from MoS2 and MoSe2 - with one side of the Janus MoSSe structure being S atoms, and the other side being Se atoms. The Mo atom layer is sandwiched between S and Se layers, and multilayers of MoSSe are stacked by the vdW interactions. Due to the the structural asymmetry and a large out-of-plane piezoelectric polarisation of Janus MoSSe, it is possible to stack the dipoles of the individual layers and obtain an atomically-thin pn-junction across the multilayer system by stacking multiple Janus MoSSe layers on top of each other.

Similar to MoS2, the MoSSe monolayer also exhibits a honeycomb pattern from the top view of the lattice. However, the mirror symmetry is broken due to the different electronic properties of sulfur and selenium, which leads to the polar properties of MoSSe.

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.
