Dimerization-Induced Cross-Layer Quasi-Two-Dimensionality in Metallic Iridate IrTe2

G. L. Pascut, K. Haule, M. J. Gutmann +7

The crystal structure of layered metal IrTe2 is determined using single-crystal x-ray diffraction. At T=220 K, it exhibits Ir and Te dimers forming a valence-bond crystal. Electron…
