Nonlinear Optical Response of SrTiO3/LaAlO3 Superlattices
N. Ogawa, K. Miyano, M. Hosoda +4
The electronic symmetry of the SrTiO3/LaAlO3 interface was investigated by optical second harmonic generation, using superlattices with varying periodicity to study the evolution o…
Termination Control of the Interface Dipole in LaSrMnO/Nb:SrTiO (001) Schottky Junctions
Yasuyuki Hikita, Mitsuru Nishikawa, Takeaki Yajima +1
In order to investigate the interface termination dependence of perovskite band alignments, we have studied the Schottky barrier height at LaSrMnO/Nb:SrTiO…
Electronic structure of the SrTiO/LaAlO interface revealed by resonant soft x-ray scattering
H. Wadati, D. G. Hawthorn, J. Geck +11
We investigated the electronic structure of the SrTiO/LaAlO superlattice (SL) by resonant soft x-ray scattering. The (003) peak, which is forbidden for our "ideal" SL struc…
Negative Differential Resistance Induced by Mn Substitution at SrRuO3/Nb:SrTiO3 Schottky Interfaces
Y. Hikita, L. Fitting Kourkoutis, T. Susaki +3
We observed a strong modulation in the current-voltage characteristics of SrRuO/Nb:SrTiO Schottky junctions by Mn substitution in SrRuO, which induces a metal-insulator…
Optically tuned dimensionality crossover in photocarrier-doped SrTiO: onset of weak localization
Y. Kozuka, Y. Hikita, T. Susaki +1
We report magnetotransport properties of photogenerated electrons in undoped SrTiO single crystals under ultraviolet illumination down to 2 K. By tuning the light intensity, th…
Characterization of the Schottky Barrier in SrRuO3/Nb:SrTiO3 Junctions
Y. Hikita, Y. Kozuka, T. Susaki +2
Internal photoemission spectroscopy was used to determine the Schottky barrier height in rectifying SrRuO3/Nb-doped SrTiO3 junctions for 0.01 wt % and 0.5 wt % Nb concentrations. G…
