Article Preview

We report on photoemission studies of SrTiO3, Pr0.55(Ca1-ySry)0.45MnO3 (PCSMO, y=0.25,0.40), and Ti1-xCoxO2-δ (x=0.05, 0.10) under laser illumination and discuss the origins of the unusual electronic structure changes induced by optical excitation at the surfaces of these transition-metal oxides. The present study shows that photoemission spectroscopy is a powerful tool to explore novel photo-induced electronic states which can open up possibilities of new optical devices.
