An efficient screening procedure for two-dimensional (2D) solid-electrolyte interphases (SEIs) is designed. In the concrete case, the two selected 2D SEIs (h-BN and α-BNyne) do stabilize the interface between the solid-state electrolyte Li10GeP2S12 and the lithium metal anode, blocking the electron transfer and maintaining the Li-ion flow.
Abstract
Since the discovery of graphene, two-dimensional (2D) layered materials have always been the focus of material research. The layers of 2D materials are covalent bonds, and the layers are weakly bonded to adjacent layers through van der Waals (vdW) interactions. Since any dangling-bond-free surface could be combined with another material through vdW forces, the concept can be extended. This can refer to the integration of 2D materials with any other non-2D materials through non-covalent interactions. The emerging mixed-dimensional (2D+nD, where n is 0, 1 or 3) heterostructure devices has been studied and represents a wider range of vdW heterostructures. New electronic devices and optoelectronic devices based on such heterojunctions have unique functions. Therefore, this article depicts the research progress of (2D+nD, where n is 0, 1 or 3) vdW heterojunctions based on 2D materials.
Since the successful preparation of single-layer graphene in 2004, two-dimensional materials have gradually become one of the research hotspots in the field of materials science. However, due to the inevitable defects of intrinsic two-dimensional materials, researchers began to explore how to obtain more excellent two-dimensional materials. In this paper, the basic properties, preparation methods and application in gas sensors of MoS2/rGO composites are reviewed. This paper has a certain reference value for the research of two-dimensional materials used in gas sensors.
