We propose a study to characterize diffusive motion of muonium, charge cycles and Mu0 states in vanadium dioxide (VO2) using zero and longitudinal field muon spin depolarization and low transverse field muon spin rotation measurements. To achieve a full characterization of these features, we plan to scan a temperature range of 5 K to at least 600 K, which traverses the metal to semiconducting phase transition (~340K) of VO2. The main objectives are to understand the muonium dynamics, states and charge cycles throughout the various phases of this material to provide insight into the role that hydrogen plays leading up to and within the transition as well as the early time history of the hydrogen defect in this material. Incorporating hydrogen in VO2 has been shown to lower the transition temperature but the role that hydrogen plays in that process has not been probed experimentally.
