Bernhard We have measured the temperature dependence of the direct band gap E g in SrTiO 3 and BaTiO 3 and related materials with quantum-paraelectric and ferroelectric properties using optical spectroscopy. We show that E g exhibits an anomalous temperature dependence with pronounced changes in the vicinity of ... [Phys. Rev. B 88, 104110] Published Thu Sep 26, 2013
