Abstract: 
In semiconducting transition metal oxides, e.g. Co1-delta-O, an electronic flux may be induced indirectly by an ion flux even in the absence of its own direct cause, a gradient of the electronic electrochemical potential. The magnitude of this cross effect is determined by the charge of transport, alpha-Co, of the migrating ion, the absolute value of which may be interpreted as the number of electrons dragged by a Co2+ or the number of holes dragged by a V"(Co). The formal and exhaustive analysis of this phenomenon is made on the basis of a proper distinction between building units and structure elements of the crystal. A preliminary result of the experimental determination of the cross effect, and the reanalysis of the literature data reveal that, for Co1-delta-O with V'(Co) prevailing, alpha-Co is by no means negligible. The implications and consequences of this non-zero cross effect are discussed.
