摘要:

The chemical diffusion of oxygen and the structure of the electronic defects in undoped and transition metal doped YSZ single crystals have been investigated by a contactless relaxation technique and magneto-optical resonance (MCD(A))-studies. The local structure and the transport properties of YSZ (9.5 mol% Y2O3) are interrelated by the actual defect distribution of 7- and 6-fold coordinated Zr-defects with trigonal symmetry which mainly originate from Zr d- conduction band tail states and act as electron traps.
