In particular, we studied manganite-titanate p-n heterojunctions made of n-doped SrTi1-yNbyO3, y = 0.002 and p-doped Pr1-xCaxMnO3, x = 0.34 having a strongly correlated electron system. The diffusion length of the polaron carriers was analyzed by electron beam-induced current (EBIC) in a thin cross plane lamella of the junction. In the J-V characteristics, the polaronic nature of the charge carriers is exhibited mainly by the temperature dependence of the microscopic parameters, such as the hopping mobility of the series resistance and a colossal electro-resistance (CER) effect in the parallel resistance. We conclude that a modification of the Shockley equation incorporating voltage-dependent microscopic polaron parameters is required. Specifically, the voltage dependence of the reverse saturation current density is analyzed and interpreted as a voltage-dependent electron-polaron hole-polaron pair generation and separation at the interface."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft (DFG), project B02 [SFB1073]"],["dc.identifier.doi","10.3762/bjnano.6.152"],["dc.identifier.isi","000357558400001"],["dc.identifier.pmid","26199851"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36591"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation","SFB 1073: Kontrolle von Energiewandlung auf atomaren Skalen"],["dc.relation","SFB 1073 | Topical Area B | B02 Photonen-getriebener Energietransfer über Grenzflächen zwischen Materialien mit starken Korrelationen"],["dc.relation.issn","2190-4286"],["dc.relation.orgunit","Institut für Materialphysik"],["dc.rights","CC BY 2.0"],["dc.title","Current-voltage characteristics of manganite-titanite perovskite junctions"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
