Coexistence of two- and three-dimensional Shubnikov-de Haas oscillations in Ar^+ -irradiated KTaO_3
S. Harashima, C. Bell, M. Kim +3
We report the electron doping in the surface vicinity of KTaO_3 by inducing oxygen-vacancies via Ar^+ -irradiation. The doped electrons have high mobility (> 10^4 cm^2/Vs) at low t…
Scanning SQUID Susceptometry of a paramagnetic superconductor
J. R. Kirtley, B. Kalisky, J. A. Bert +8
Scanning SQUID susceptometry images the local magnetization and susceptibility of a sample. By accurately modeling the SQUID signal we can determine the physical properties such as…
Common Origin of the Circular-dichroism Pattern in ARPES of SrTiO3 and CuxBi2Se3
Y. Ishida, H. Kanto, A. Kikkawa +15
Circular dichroism in the angular distribution (CDAD) of photoelectrons from SrTiO3:Nb and CuxBi2Se3 is investigated by 7-eV laser ARPES. In addition to the well-known node that oc…
Inelastic light scattering measurements of a pressure-induced quantum liquid in KCuF
S. Yuan, M. Kim, J. Seeley +3
Pressure-dependent, low temperature inelastic light (Raman) scattering measurements of KCuF show that applied pressure above 7 kbar suppresses a previously observe…
Intrinsic spin-orbit coupling in superconducting δ-doped SrTiO3 heterostructures
M. Kim, Y. Kozuka, C. Bell +2
We report the violation of the Pauli limit due to intrinsic spin-orbit coupling in SrTiO3 heterostructures. Via selective doping down to a few nanometers, a two-dimensional superco…
Dominant mobility modulation by the electric field effect at the LaAlO_3 / SrTiO_3 interface
C. Bell, S. Harashima, Y. Kozuka +4
Caviglia et al. [Nature (London) 456, 624 (2008)] have found that the superconducting LaAlO_3 / SrTiO_3 interface can be gate modulated. A central issue is to determine the princip…
