Abstract
Ionic and electronic currents can coexist in the so-called mixed ionic electronic conductors (MIEC). When these conductors interact with non-uniform chemical surroundings, electrical currents are induced in the MIEC. Applied electric fields affect not only the ionic and electronic currents, but also induce chemical changes in the MIEC. Under certain conditions a quasi p-n or p-i-n junction is formed, the structure of which depends on the applied voltage.
This lecture deals with the I-V characteristics and four point conductivity measurements performed on mixed ionic electronic conductors as well as induced chemical changes. The possible use of a MIEC in a fuel cell is also discussed.
