van der Waals Epitaxy of 2D materials — •Sefaattin Tongay — Arizona State University, USA
Van der Waals (vdW) epitaxy is a common technique used for production of 2D materials systems. Owing to their chemically passivated surfaces, vdW epitaxy does require any lattice match and a number of 2D transition metal dischalcogenide (TMDCs) and post-transition metal chalcogenides (PTMCs) can be deposited onto various oxide surfaces. Since the underlying substrate and 2D materials weakly interact with each other, vdW epitaxy anticipated to produce 2D systems with material properties closely similar to that of exfoliated ones. This talk will focus on how underlying substrates influence the material properties through interation with 2D layered materials, and introduce colossal band renormalization in some unique systems.
