Giant strain gradient elasticity in SrTiO3 membranes: bending versus stretching
Varun Harbola, Samuel Crossley, Seung Sae Hong +4
Young's modulus determines the mechanical loads required to elastically stretch a material, and also, the loads required to bend it, given that bending stretches one surface while…
Transistor operation and mobility enhancement in top-gated LaAlO_3 / SrTiO_3 heterostructures
M. Hosoda, Y. Hikita, H. Y. Hwang +1
We report the operation of LaAlO_3 / SrTiO_3 depletion mode top-gated junction field-effect transistors using a range of LaAlO_3 thicknesses as the top gate insulator. Gated Hall b…
Stoichiometry control of the electronic properties of the LaAlO_3/SrTiO_3 heterointerface
H. K. Sato, C. Bell, Y. Hikita +1
We investigate the effect of the laser parameters of pulsed laser deposition on the film stoichiometry and electronic properties of LaAlO_3/SrTiO_3 (001) heterostructures. The La/A…
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…
Subband structure of a two-dimensional electron gas formed at the polar surface of the strong spin-orbit perovskite KTaO
P. D. C. King, R. H. He, T. Eknapakul +13
We demonstrate the formation of a two-dimensional electron gas (2DEG) at the surface of the transition-metal oxide KTaO. From angle-resolved photoemission, we find…
