We have investigated the tunneling transport of mono-and few-layers of MnPS3 by using conductive atomic force microscopy. Due to the band alignment of indium tin oxide/MnPS3/Pt-Ir tip junction, the key features of both Schottky junction and Fowler-Nordheim tunneling (FNT)were observed for all the samples with varying thickness. Using the FNT model and assuming the effective electron mass (0.5 me) of MnPS3, we estimate the tunneling barrier height to be 1.31 eV and the dielectric breakdown strength as 5.41 MV/cm. The discovery of graphene and its rich physics subsequently unearthed have literally revolutionized the field of van der Waals (vdW) materials and the list of newly found vdW systems are exploding at a fast pace 1-3 . However, it became clear soon after the initial discovery that although the zero band gap of graphene renders the associated physic fascinating, at the same time it poses serious problems for potential applications using graphene. This realization has driven more recent searches for vdW materials with a sizeable band gap such as hexagonal boron nitride and transition metal di-chalcogenides (TMDCs). 4 Upon close inspection of the ever growing list of the vdW materials, however one can take an immediate note of the fact that there is hardly any magnetic vdW system in the list, with the only a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
