Query: Top-seeded solution growth of SrTiO3 crystals and phase diagram studies
  in the SrO-TiO2 system   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.
