What Are 2D and Topological Materials Good For?
I will discuss whether 2D semiconductors and topological semimetals could play a role in future electronics. Their ultrathin nature provides some advantages for flexible electronics [1],light-weight solar cells [2], nanoscale transistors [3], and interconnects [4], but they are not ideal where conventional materials work sufficiently well. I will dive deeper into monolayer 2D semiconductors as energy-efficient transistors[5-8], discuss the effects of strain on their operation [8,9], and outline fundamental challenges that remain. I will also describe ultrathin chalcogenides for phase-change memory [10] and ultrathin topological semimetals as future interconnects [4]. If time permits, I will discuss potential thermal management advances using 2D materials [12,13] and nitrides with good thermal conductivity[14]. Combined, these studies reveal some fundamental limits and practical applications of emerging materials for future electronics.
