Fermi surface and superconductivity in low-density high-mobility δ-doped SrTiO3
M. Kim, C. Bell, Y. Kozuka +3
The electronic structure of low-density n-type SrTiO3 delta-doped heterostructures is investigated by angular dependent Shubnikov-de Haas oscillations. In addition to a controllabl…
Enhancing the electron mobility via delta-doping in SrTiO3
Y. Kozuka, M. Kim, H. Ohta +3
We fabricated high-mobility δ-doped structures in SrTiO3 thin films in order to investigate the low temperature electronic transport properties of confined carriers in this system.…
Dramatic Mobility Enhancements in Doped SrTiO3 Thin Films by Defect Management
Y. Kozuka, Y. Hikita, C. Bell +1
We report bulk-quality n-type SrTiO3 (n-SrTiO3) thin films fabricated by pulsed laser deposition, with electron mobility as high as 6600 cm2 V-1 s-1 at 2 K and carrier density as l…
Thickness dependence of the mobility at the LaAlO_3 / SrTiO_3 interface
C. Bell, S. Harashima, Y. Hikita +1
The electronic transport properties of a series of LaAlO_3 / SrTiO_3 interfaces were investigated, and a systematic thickness dependence of the sheet resistance and magnetoresistan…
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…
Vanishing Hall Coefficient in the Extreme Quantum Limit in Photocarrier-Doped SrTiO3
Y. Kozuka, T. Susaki, H. Y. Hwang
We have investigated the extreme quantum limit of photogenerated electrons in quantum paraelectric SrTiO3. This regime is distinct from conventional semiconductors, due to the larg…
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…
