Largely Enhanced Mobility in Trilayered LaAlO 3 /SrTiO 3 /LaAlO 3 Heterostructures

LaAlO3 (LAO)/SrTiO3 (STO)/LaAlO3 (LAO) heterostructures were epitaxially deposited on TiO2-terminated (100) SrTiO3 single crystal substrates by laser molecular beam epitaxy. The electron Hall mobility of 1.2x10^4 cm2/Vs at 2 K was obtained in our …
