Large scale synthesis of monolayer ferromagnetic Fe3GeTe2

ORAL

Abstract

Until now, the two-dimensional ferromagnets remain limited to exfoliated micron-sized samples. Large-scale thin films are desirable for the fabrication of integrated devices for spintronic and memory storage applications. We show, by molecular beam epitaxy, the synthesis of high-quality Fe3GeTe2 (FGT) films, a promising candidate that carries ferromagnetic states at room temperature upon ionic liquid gating. The FGT unit cell consists of two weakly coupled quintuple layer substructures with hexagonal symmetry, confirmed by surface x-ray diffraction.
