Professor Balandin gave an invited talk at the Materials Research Society (MRS) Fall 2020 Meeting in the virtual format. The invited talk entitled “Unique properties of quasi-one-dimensional and mixed dimensional van der Waals heterostructures” was delivered at the Symposium – Advanced Manufacturing of Mixed Dimensional Heterostructures. The talk is available on demand at MRS web- site. Two-dimensional (2D) materials, such as graphene and transition metal dichalcogenides (TMDs) have revealed new physics and demonstrated potential for practical applications. In recent years, interest in layered van der Waals materials has expanded to quasi-one-dimensional (1D) structures. Unlike the layered TMD materials that yield 2D layers upon exfoliation, the transition metal trichalcogenides (TMTs) contain 1D motifs, i.e. atomic threads, that are weakly bound together by van der Waals forces. The TMT crystals can exfoliate into bundles of atomic threads. This invited talk reviews synthesis methods, properties and possible device applications of this unique family of quasi-1D TMT material systems. The presentation slides for this invited MRS talk are are available at the link.
