Merohedral disorder and impurity impacts on superconductivity of fullerenes

Abstract

Doped-fullerenes are a class of organic superconductors where disorder can be used to tune the superconducting temperature as well as the presence of subgap excitations such as Yu-Shiba-Rusinov states. Here, the authors investigate how structural disorder and non-magnetic impurities affect the superconductivity of Rb-doped fullerenes and what information this can provide about the underlying mechanisms.
