Induced p-type semiconductivity in yttria-stabilized zirconia

8 mol% yttria-stabilized zirconia (8YSZ) ceramic is an oxide ion conductor at atmospheric pressure but shows the onset of p-type semiconduction, in addition to the preexisting oxide ion conduction, on application of a dc bias in the range 4-66 Vcm-1 and at temperatures in the range 150°C-750°C. The...
