Heterogeneous ferroelectricity and conductivity of oxidized BaTiO crystals: the role of nanoscale phase segregation in the surface region
Christian Rodenbücher, Gustav Bihlmayer, Susan Trolier-McKinstry +3
We investigate the effect of thermal oxidation on BaTiO single crystals. Our results reveal that, even at moderate temperatures of up to 1000 °C, complex segregation mechanisms…
A physical method for investigating defect chemistry in solid metal oxides
Christian Rodenbücher, Carsten Korte, Thorsten Schmitz-Kempen +2
The investigation of the defect chemistry of solid oxides is of central importance for the understanding of redox processes. This can be performed by measuring conductivity as a fu…
Inhomogeneity of donor doping in SrTiO3 substrates studied by fluorescence-lifetime imaging microscopy
C. Rodenbücher, T. Gensch, W. Speier +7
Fluorescence-lifetime imaging microscopy (FLIM) was applied to investigate the donor distribution in SrTiO3 single crystals. On the surfaces of Nb- and La-doped SrTiO3, structures…
