Temperature anomalies in transition-metal-oxides and their correlations with photocatalytic activity: structural, dielectric and electrical characterisation of titania systems Hantusch, Martin , 1990- (VerfasserIn) Burkel, Eberhard , 1952- (AkademischeR BetreuerIn) Bessergenev, Valentin (AkademischeR BetreuerIn) Universität Rostock (Grad-verleihende Institution) Universität Rostock Mathematisch-Naturwissenschaftliche Fakultät (Grad-verleihende Institution) Text theses Text Hochschulschrift 2017 2017 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource Annealing titania in vacuum while an external electrical field was applied resulted in the observation of structural, morphological and electrical anomalies. However, treating titania in vacuum leads to a redistribution of lattice defects. The diffusion of these lattice defects forms charge carrier trapping sites and permanent dipoles. The alignment of these dipoles leads to the formation of anisotropic conductive channels. Furthermore, the redistribution of lattice defects results in a new crystalline phase.<eng> vorgelegt von Martin Hantusch GutachterInnen: Eberhard Burkel (Universität Rostock) ; Valentin Bessergenev (Universidade do Algarve) Dissertation Universität Rostock 2018 530 http://purl.uni-rostock.de/rosdok/id00002487 Temperature anomalies in transition-metal-oxides and their correlations with photocatalytic activity--(DE-627)1670166724 urn:nbn:de:gbv:28-rosdok_id00002487-6 doi: 10.18453/rosdok_id00002487 oclc: 1135498297 ppn: (DE-627)1669244024
