Alex Balandin of University of California, Riverside

In this invited talk, I will describe the properties and device applications of quasi-two-dimensional (2D) and quasi-one-dimensional (1D) van der Waals materials. The 2D van der Waals materials include graphene and the transition metal dichalcogenides (TMD), which exfoliate or grow into quasi-2D atomic layers. The focus will be on 1T-TaS₂, a unique material with charge-density-wave (CDW) quantum phases, observed even above room temperature. The 1D van der Waals materials include members of the transition metal trichalcogenide (TMT) family, which exfoliate or grow into quasi-1D atomic threads or atomic chains. I will discuss electric bias switching among various CDW quantum phases in 1T-TaS₂ and possibilities of their device applications [1-3]; current carrying capacity of TaSe₃ atomic bundles [4]; the use of 1D materials in composites for electromagnetic interference shielding and in the next generation of communication systems [5]. This work was supported, in part, by DOE, SRC, and NSF DMREF.
