Temperature dependent percolation mechanism for conductivity in Y${}_{0.63}$Ca${}_{0.37}$TiO${}_3$ revealed by a microstructure study

R. German, B. Zimmer, T. C. Koethe +5

We have performed optical microscopy, micro-photoelectron spectroscopy, and micro-Raman scattering measurements on Y${}_{0.63}$Ca${}_{0.37}$TiO${}_3$ single crystals in order to clarify…
