摘要：

The microscopic mechanism of the phase transition of SrTiO3 at 110 K is discussed in terms of Kristoffel's electronic band model of the structural phase transition. The lowering of the valence-state energy with phonon excitation is calculated including the Sr-O interaction. It is demonstrated that the lowering of the valence-electron energy is larger than the short-range elastic energy of phonon excitation. © 1978 The American Physical Society.
