Gate-defined Josephson weak-links in monolayer
Michael D. Randle, Masayuki Hosoda, Russell S. Deacon +9
Systems combining superconductors with topological insulators offer a platform for the study of Majorana bound states and a possible route to realize fault tolerant topological qua…
Josephson junctions of Weyl semimetal induced by spontaneous nucleation of superconductor
Manabu Ohtomo, Russell S. Deacon, Masayuki Hosoda +7
We report on the fabrication of Josephson junction devices with weak links utilizing the Weyl and higher-order topological semimetal . We show that $\text{WTe}_2\text…
Separation of Charge Instability and Lattice Symmetry Breaking in an Organic Ferroelectric
Ryosuke Takehara, Keishi Sunam, Fumitatsu Iwase +5
We investigate the charge and lattice states in a quasi-one-dimensional organic ferroelectric material, TTF-QCl, under pressures of up to 35 kbar by nuclear quadrupole resona…
The potential profile at the LaAlO3/SrTiO3 (001) heterointerface in operando conditions
M. Minohara, Y. Hikita, C. Bell +7
We report measurements of the gate-bias dependent band alignment, especially the confining potential profile, at the conducting LaAlO3/SrTiO3 (001) heterointerface using soft and h…
Locally enhanced conductivity due to the tetragonal domain structure in LaAlO/SrTiO heterointerfaces
Beena Kalisky, Eric M. Spanton, Hilary Noad +14
The ability to control materials properties through interface engineering is demonstrated by the appearance of conductivity at the interface of certain insulators, most famously th…
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…
Measurements of the gate tuned superfluid density in superconducting LaAlO3/SrTiO3
Julie A. Bert, Katja C. Nowack, Beena Kalisky +8
The interface between the insulating oxides LaAlO3 and SrTiO3 exhibits a superconducting two-dimensional electron system that can be modulated by a gate voltage. While gating of th…
Critical thickness for ferromagnetism in LaAlO3/SrTiO3 heterostructures
Beena Kalisky, Julie A. Bert, Brannon B. Klopfer +6
In heterostructures of LaAlO3 (LAO) and SrTiO3 (STO), two nonmagnetic insulators, various forms of magnetism have been observed [1-7], which may [8, 9] or may not [10] arise from i…
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…
