Abstract Scope |
2D materials, which include graphene, hexagonal boron nitride, and a plethora of transition metal dichalcogenide (TMDC) combinations, have electronic structures exhibiting metallic, semiconducting, and insulating properties. This promises devices with scalability to the atomic limit combined with tunable bandgaps that can be direct or indirect and defect free interfaces. Presented will be our summary of our recent work investigating the deposition of TMDCs on ferroelectric and linear dielectric substrates. We will show how deposition conditions can impact not just the grown material, but also the substrate. During growths, chalcogens can diffuse into oxide substrates resulting in Fermi level shifts which we speculate is due to oxygen vacancy passivation. This will be important for integration of these materials into nanoelectronics device architectures. |
