Crystal Structure – Fe0.25TaSe2

Crystal Structure – Fe0.33TaSe2

Structural property summary

  • Single crystal form: black color, metallic luster, Plate-like
  • Structure type: layered, Hexagonal, P63/mmc (x=0.25) or P6322 (x=0.33)
  • Air sensitivity: Relatively stable. Degrade after long time. 
  • Exfoliation capability: exfoliable, but not easy to thin down to atomically thin layers
  • Note: the Fe content can change between 0.25 to 0.33, which causes drastic changes in the magnetic ordering temperature.
