MSE Seminar: “In-Situ Resistance Degradation & Switching of Bulk Fe-doped SrTiO3 and Yttria-Stabilized Zirconia”
Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United StatesPerovskite-type titanates are the standard dielectric used in multilayer ceramic capacitors (MLCCs), and yttria-stabilized (YSZ) is the prototypical fast oxygen conductor used in solid oxide fuel cells (SOFCs) and oxygen sensors. Under a DC electric field, the resistance of YSZ and Fe-doped strontium titanate (Fe-STO) degrades in an indistinguishable way. This is surprising because, unlike […]
