Abstract

The TiO2 rich part of the (1-x) SrO + x TiO2 phase diagram 0.5 <= x <= 1.0 was redetermined and the eutectic point between SrTiO3 and TiO2 was found at x_eut=0.7700+/-0.0001; T_eut=(1449+/-3) deg C. From TiO2 rich melt solutions, x=0.75 centimeter-sized single crystals could be grown. The best crystals with etch pit density <2 x 10^4/cm^2 were obtained for growth directions <110> and <100>. AFM investigation of the interface reveals layer-by-layer growth.
