Of particular interest is a class of materials called transition metal dichalcogenides (TMDs). The materials within this class were discovered to show similarly intriguing optical and electronic properties, when compared to graphene. Moreover, research indicated that these properties are also highly sensitive to the TMDs' underlying atomic structure. Gaining control over these structural properties would enable the tuning of the physical and chemical properties, and hence allow for the fabrication of novel TMD nanostructures with tailored functionalities. Driven by this potential, we strive to gain a comprehensive understanding of the relationship between the structural, chemical, and local electronic properties of nanostructures based on one such TMD material: tungsten disulfide (WS2). This in order to aid us in the exploitation of the tunability of these physical properties through the fabrication of novel WS2 nanostructures. … Subject Transition metal dichalcogenides (TMDs)NanostructuresChemical vapor deposition (CVD)Transmission electron microscopy (TEM)Electron energy-loss spectroscopy (EELS)Four-dimensional scanning transmission electron microscopy (4D-STEM)Electron microscope pixel array detector (EMPAD) To reference this document use: https://doi.org/10.4233/uuid:b9cf52ab-06fa-40bf-882e-96a72d8e234d ISBN 978-94-6384-557-1 Part of collection Institutional Repository Document type doctoral thesis Rights © 2024 S.E. van Heijst Files PDF Dissertation_SEvanHeijst_final.pdf 32.78 MB PDF Propositions_SEvanHeijst_V2.pdf 143.43 KB Close viewer /islandora/object/uuid:b9cf52ab-06fa-40bf-882e-96a72d8e234d/datastream/OBJ1/view
