Static and ultrafast dynamics of defects of SrTiO3 in LaAlO3/SrTiO3 heterostructures [PDF]
Applied Physics Letters, 2011 A detailed defect energy level map was investigated for heterostructures of 26 unit cells of LaAlO3 on SrTiO3 prepared at a low oxygen partial pressure of 10−6 mbar. The origin is attributed to the presence of dominating oxygen defects in SrTiO3 substrate.
