Transmission electron microscopy of dislocations in SrTiO3

Dislocations have been introduced in SrTiO3 by Vickers indentation at room temperature and analysed by transmission electron microscopy. The slip systems in SrTiO3 were identified as [110]-{110}. [110] dislocations are dissociated into two partial dislocations. The stacking-fault energy gamma(SF) was determined to be 136 +/- 15 mJ m(-2).
