| Abstract |
Electric charge transport is an essential process for all electrical and electrochemical energy systems, including inanimate and animate matter. In this issue on materials for energy conversion, we compare and discuss the role of electron holes and protons as charge carriers in solids. Specifically we outline how the temperature or thermal bath affect the charge carrier concentration and mobility for some metal oxides with the perovskite structure. The frequent observation that the conductivity becomes independent of the activation energy at the isokinetic temperature, known as the Meyer-Neldel rule, is an important aspect of our interpretation of the physical mechanism of conduction by polaron hopping. |
