Nanoscience of Atomically-Thin Materials

THE ABSTRACT Atomically-thin materials represent the thinnest possible components of future devices having extreme reduction in size scales. While tremendous progress has recently been made in understanding the large-scale properties of atomically-thin materials, the low-dimensional aspects, although critical to the smallest device sizes, have received much less attention. Within this important field of atomically-thin materials, I will discuss our recent experimental investigations of the synthesis and the local mechanical and electrical properties of these low-dimensional systems. These experiments on atomically-thin materials focus on their edges, ordered low-dimensional phases contained within them, integration with lower-dimensional materials (such as 1D nanotubes), and the electrical transport at extremely confined scales -- work which probes the fundamental behavior in the ultimate limits of device-size scaling.
