Abstract

Oxide ion conducting yttria-stabilised zirconia ceramics show the onset of electronic conduction under a small bias voltage. Compositions with a high yttria content undergo a transition from p-type to n-type behavior at voltages in the range 2.4 to 10 V, which also depends on oxygen partial pressure. This shows that surface reactions have a direct influence on bulk conductivities, with possible implications for voltage-induced flash phenomena and resistive switching.

Keywords: yttria-stabilized zirconia (YSZ), flash sintering, pn juction, dc bias, resistive switching, impedance spectroscopy
