Low price, high purity 2D zirconium diselenide powder and crystals

For the development of next-generation electronics, optoelectronics, and nanotechnology

Technical Data | MSDS | Structure | Literature and Reviews | Related Products | Resources and Support

Zirconium diselenide (ZrSe2, CAS number 12166-47-1) is a 2D semiconductor with a bandgap in the visibles-infrared region. With moderate bandgaps, 2D ZrSe2 and HfSe2 are believed to be among the best candidates to replace the silicon in nanoelectronics.

With the value of dimensionless thermoelectric figure-of-merit (ZT) being higher than those of MoS2 and MoSe2 monolayers, ZrSeyields high thermoelectric conversion efficiency. Furthermore, the thermoelectric performance of ZrSe2 can be effectively enhanced by band valley engineering through the application of biaxial strain.

Structure of Zirconium Diselenide

Zirconium diselenide (ZrSe2) is a 2D semiconductor with a bandgap in the visible-infrared region. ZrSecrystallizes in the CdI2 (1T) polytype with octahedral metal coordinationon: one Zr atom is octahedrally coordinated by six selenium atoms. Single layer of  ZrSe2 consists of a sequence of Se-Zr-Se atomic trilayer unit in which a sheet of Zr atoms is sandwiched between two sheets of selenides. Like other TMDCs,strong covalent bonds exist within the layer structure, while weak van der Waals holds the successive ZrSe2 layers together.

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.
