Atomic scale insights into the epitaxial growth mechanism of 2D Cr₃Te₄ on mica

Abstract

Two-dimensional (2D) magnetic materials are of wide research interest owing to their promising applications in spintronic devices. Among them, chromium chalcogenide compounds are one of the limited available systems that...

An unexpected interfacial Mo-rich phase in 2D molybdenum disulfide and 3D gold heterojunctions

“…[20][21][22][23] Such a chemical reaction process, occurring on the surface of 3D-metals, often allows chemical interaction with the surrounding vapor phase environment that induces the formation of a second phase suitable for multifunctional applications. [24][25][26][27] For instance, a highly ordered 1D intermediate crystal was observed between the MoO 2 substrate and the product 2D MoS 2 obtained through thermal sulfidation, and the subsequent thickening of MoS 2 caused a transition from a p-type to an n-type Schottky contact. 28 Our previous work demonstrated that a S-rich environment resulted in an unconventional Au 4 S 4 reconstructed phase at the interface of the Au substrate and 2D MoS 2 during the growth of MoS 2 on 3D nanoporous gold (NPG).…”
