Experimental study demonstrates epitaxial growth of insulating monolayer FeBr2 on Bi(111), indicating potential utility for two-dimensional spintronic devices.
High Resolution Image Download MS PowerPoint Slide Magnetic van der Waals (vdW) materials have attracted considerable attention in recent years because of their future spintronics applications. 3d Transition metal dihalides are a promising class of materials to realize two-dimensional vdW magnets with intriguing magnetic and electronic properties. We report the epitaxial growth of (0001)-oriented FeBr 2 films from the monolayer by molecular beam epitaxy on the Bi(111) surface. The atomic structure was confirmed to be identical to that of the bulk FeBr 2 crystal by dynamical low-energy electron diffraction analysis. Angle-resolved photoelectron spectroscopy revealed that the topmost valence band composed of Fe 3d orbitals is located at 2.2 eV below the Fermi level, showing that the FeBr 2 films are insulating down to the monolayer.
