Origin of high mobility in LaAlO3/SrTiO3 structures
We have shown, using magnetotransport measurements in high magnetic fields (SdH oscillations and Hall effect), that LAO/STO is not a 2D system, but 3D system. High mobility in this system is due to the doping of STO substrate by oxygen vacancies, and this happens during growth, but only in low oxygen pressure. In higher oxygen pressures, LAO/STO structure is no more of high mobility type.
