Transition metal dichalcogenides (TMDCs) are a versatile class of layered materials with tuneable electronic properties. One approach to tailoring these properties is to manipulate the material’s effective dimensionality. Specifically, intercalating cationic organic molecules with different alkane carbon chain into the van der Waals gaps between the layers increases the interlayer distance of the TMDC host material. This transforms the crystal from a bulk state to a monolayer-like state, thereby altering the electronic structure [1]. Here, we present a comprehensive study of the geometric and electronic structures of intercalated and non-intercalated TMDCs, such as NbSe2, using SEM, EDS, and 11eV laser-based ARPES.
