摘要

Temperature-dependent dielectric spectroscopy was used to observe multiple dielectric responses involving four sets of dielectric relaxations (DRs) in molecular beam epitaxy-deposited ultrathin (001) SrMnO₃/Nb:SrTiO₃ heterojunctions. Two sets of oxygen-vacancy (OV)-related DRs, which were sensitive to oxygen annealing, were attributed to short-range OV hopping and localized Jahn-Teller (JT)-polaron hopping-induced dipolar-type relaxations.
