Structure-Property Relation of SrTiO3-LaAlO3 Interfaces
M. Huijben, A. Brinkman, G. Koster +3
A large variety of transport properties have been observed at the interface between the insulating oxides SrTiO3 and LaAlO3 such as insulation, 2D interface metallicity, 3D bulk me…
Magnetoresistance oscillations and relaxation effects at the SrTiO3-LaAlO3 interface
M. van Zalk, J. Huijben, A. J. M. Giesbers +8
We present low-temperature and high-field magnetotransport data on SrTiO3-LaAlO3 interfaces. The resistance shows hysteresis in magnetic field and a logarithmic relaxation as a fun…
Magnetic effects at the interface between nonmagnetic oxides
A. Brinkman, M. Huijben, M. van Zalk +7
The electronic reconstruction at the interface between two insulating oxides can give rise to a highly-conductive interface. In analogy to this remarkable interface-induced conduct…
Dependence of electronic structure of SrRuO3 and the degree of correlation on cation off-stoichiometry
Wolter Siemons, Gertjan Koster, Arturas Vailionis +3
We have grown and studied high quality SrRuO3 films grown by MBE as well as PLD. By changing the oxygen activity during deposition we were able to make SrRuO3 samples that were sto…
Origin of charge density at LaAlO3-on-SrTiO3 hetero-interfaces; possibility of intrinsic doping
Wolter Siemons, Gertjan Koster, Hideki Yamamoto +5
As discovered by Ohtomo et al., a large sheet charge density with high mobility exists at the interface between SrTiO3 and LaAlO3. Based on transport, spectroscopic and oxygen-anne…
