High Mobility in LaAlO3/SrTiO3 Heterostructures: Origin, Dimensionality, and Perspectives

We have investigated the dimensionality and origin of the magnetotransport properties of ${\mathrm{LaAlO}}_{3}$ films epitaxially grown on ${\mathrm{TiO}}_{2}$-terminated ${\mathrm{SrTiO}}_{3}\left(001\right)$ substrates. High-mobility conduction is observed at low deposition oxygen pressures (${P}_... View More
