Eddleman Quantum Institute Seminar Series
In this invited seminar, I will describe 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 transition metal dichalcogenides (TMD), which exfoliate or grow into quasi-2D atomic layers. The focus will be on 1T-TaS2, a unique quantum material with charge-density-wave (CDW) 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 bundles of quasi-1D atomic chains. I will discuss electric 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 (EMI) shielding [5].

Alexander A. Balandin received his BS and MS degrees Summa Cum Laude in Mathematics and Applied Physics from the Moscow Institute of Physics and Technology, Russia; and PhD degree in Electrical Engineering from the University of Notre Dame, USA. He is presently a Distinguished Professor of Electrical and Computer Engineering, and the University of California Presidential Chair Professor of Materials Science and Engineering. He also serves as Deputy Editor-in-Chief of the Applied Physics Letters. His research expertise covers nanotechnology, materials science, electronics, solid-state physics and phononics fields. Professor Balandin is a recipient of The MRS Medal from the Materials Research Society for discovery of graphene thermal properties and the Pioneer of Nanotechnology Award from IEEE for his nano-phononics research. He is an elected Fellow of MRS, APS, IEEE, OSA, SPIE and AAAS. Since 2015, each year, he has been among the Clarivate Analytics Highly Cited Researchers – a distinction that recognizes the world's most influential researchers of the past decade by citations in the Web of Science. In 2021, Professor Balandin was named The Vannevar Bush Faculty Fellow – the most prestigious single-investigator DOD award with $3M multi-year funding that “supports new, out-of-the-box ideas where research creativity intersects with the unknown.” For more information, visit: https://balandingroup.ucr.edu/
