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

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


Zirconium diselenide (ZrSe2) is a 2D semiconductor with a bandgap in the visible-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.

We supply low price zirconium diselenide in several different forms for a range of applications.

Structure and Properties of Zirconium Diselenide

After exfoliation of zirconium diselenide crystal or powder, zirconium diselenide typically has the following properties:

  • ‎Octahedral (1T, space group: P3m1)
  • A bandgap in the visible-infrared region (0.9 ~ 1.2 eV)
  • High thermoelectric conversion efficiency
  • Thermoelectric performance of ZrSe2 can be effectively enhanced by biaxial strain

Applications of Zirconium Diselenide

Zirconium diselenide (ZrSe2) single crystals can be used to prepare monolayer and few-layer ZrSe2 by mechanical or liquid exfoliation. 

Zirconium diselenide powder is suitable for liquid chemical exfoliation to prepare ZrSe2 nanosheets and nanoparticles down to few-layer films.

Zirconium diselenide has the size of the bandgap comparable to that of silicon, which is small enough on the one hand to allow low-voltage operation, while large  enough on the other hand to enable >10on/off current ratios. ZrSe2 has great application potentials in FTEs and photovoltaic devices.

ZrSe2 and HfSe2 possess band gaps of 0.9 to 1.2 eV from bulk to ultrathin nano-structures and technologically desirable “high-κ” native dielectrics ZrO2 and HfO2, respectively. With the possibility of thinner circuits and desirable high-k insulation combined, these ultrathin semiconductors could be made into transistors 10 times smaller than anything possible with silicon.

    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.
