Atomically Thin MoS₂: A Versatile Nongraphene 2D Material

TLDR

Two‑dimensional inorganic materials, especially transition metal dichalcogenides such as MoS₂, are emerging as a premier class for modern electronic and optoelectronic devices due to their novel functionalities and broad applicability. This review surveys progress in mono‑ and few‑layer MoS₂, focusing on how crystal, phonon, and electronic structures evolve with layer number. The review details growth methodologies for single or few‑layer MoS₂, its versatility across device applications, and recent advances in van der Waals heterostructures.

Abstract

Two‐dimensional inorganic materials are emerging as a premiere class of materials for fabricating modern electronic devices. The interest in 2D layered transition metal dichalcogenides is especially high. Particularly, 2D MoS 2 is being heavily researched due to its novel functionalities and its suitability for a wide range of electronic and optoelectronic applications. In this article, the progress in mono/few layer(s) MoS 2 research is reviewed by focusing primarily on the layer dependent evolution of crystal, phonon, and electronic structure. The review includes extensive detail into the methodologies adapted for single or few layer(s) MoS 2 growth. Further, the review covers the versatility of 2D MoS 2 for a broad range of device applications. Recent advancements in the field of van der Waals heterostructures are also highlighted at the end of the review.
