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…
