Abstract

A number of group III-metal oxides are studied via density functional theory in order to establish a possibility of nonthermal transition of these materials into a superionic state. Atomic and electronic properties of the materials are analyzed during the transitions to acquire insights into physical mechanisms guiding such transformations. This knowledge is then used to suggest a criterion allowing to predict the possibility of such transitions without employing computationally heavy methods.
