Physical Behavior of Layered Superatomic Crystals

Abstract

In this project, we will focus on a family of layered superatomic crystals (SACs) assembled from two-dimensional (2D) sheets of metal chalcogenide superatoms and fullerenes (e.g. C60s and C70s). We will study how structure of the layers can integrate with orientational disorder to predictably tune material properties for Army-relevant applications such as infrared (IR) detection, thermoelectric and pyroelectric energy conversion, and thermal switching. Goals include: Synthesis of new layered SACs, measurement of thermal transport properties in new layered SACs, and simulation of thermal transport properties in new layered SACs. Due to the similarity in samples and experimental tools we have also considered layered perovskites, metal organic frameworks, covalent organic frameworks, and layered van der waals metals such as TaFeTe4.
