Abstract: X36.00004 : Van der Waals Bonded Materials: From Quasi-2D to Quasi-1D*
8:36 AM–9:12 AM
The advent of graphene stimulated interest to other two-dimensional (2D) van der Waals materials. In the first part of my talk, I will describe interesting phenomena emerging in 2D transition metal dichalcogenides (TMDs), which reveal charge density wave (CDW) phases [1-2]. Bonding and integrating three different 2D materials, 1T-TaS2, graphene and h-BN, in a way that exploited the unique characteristics of each, we were able to demonstrate a voltage controlled oscillator (VCO) functioning at room temperature . In the second part of my talk, I will explain why the research of 2D materials should be extended to the one-dimensional (1D) van der Waals materials. Using transition metal trichalcogenides (TMTs) such as TaSe3 we demonstrated prototype “atomic wire” interconnects with extraordinary current density [3-4]. I will present results, which show that integration of quasi-2D and quasi-1D van der Waals materials can lead to new functionality, previously not achievable.
