Two-dimensional superconducting diode effect in topological insulator/superconductor heterostructure
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
The superconducting diode effect (SDE) is characterized by the nonreciprocity of Cooper-pair motion with respect to current direction. In three-dimensional (3D) materials, SDE resu…
Control of nonreciprocal charge transport in topological insulator/superconductor heterostructures with Fermi level tuning and superconducting-layer thickness
Soma Nagahama, Yuki Sato, Minoru Kawamura +7
Nonreciprocal charge transport (NCT) is defined as a phenomenon where electrical resistance depends on the current direction. It has been drawing much attention because it sensitiv…
Molecular beam epitaxy of superconducting FeSeTe thin films interfaced with magnetic topological insulators
Yuki Sato, Soma Nagahama, Ilya Belopolski +7
Engineering heterostructures with various types of quantum materials can provide an intriguing playground for studying exotic physics induced by the proximity effect. Here, we repo…
Molecular beam epitaxy of superconducting SnInTe thin films
M. Masuko, R. Yoshimi, A. Tsukazaki +4
We report a systematic study on the growth conditions of SnInTe thin films by molecular beam epitaxy for maximization of superconducting transition temperature $T_\math…
