WITHDRAWN (NO REG) EL19.18.05 Developing and Integrating Atomically Thin Metals, Semiconductors and Insulators

WITHDRAWN (NO REG) 12.11.2023 EL19.18.05 The last decade has seen an exponential growth in the science and technology of two-dimensional materials. Beyond graphene, there is a huge variety of layered materials that range in properties from insulating to superconducting. Furthermore, heterogeneous stacking of 2D materials also allows for additional “dimensionality” for material and device engineering. In this talk, I will discuss recent breakthroughs in two-dimensional atomic layer synthesis, properties, and integration toward advancing devices relevent to the semicondcutor industry. This includes novel 2D heterostructures and the realization of unique 2D allotropes of 3D materials (e.g. 2D metals, nitride, oxides) based on a novel synthesis method, dubbed confinement heteroepitaxy (CHet). By shrinking traditional metals to atomically thin structures, we find that their properties are completely different than their bulk counterparts, lending themselves to unique quantum and optical applications not possible before.
