Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Self-Consistent Model for Gate Control of Narrow-, Broken-, and Inverted-Gap (Topological) Heterostructures
Maximilian Hofer, Christopher Fuchs, Moritz Siebert +8
Even small electrostatic potentials can dramatically influence the band structure of narrow-, broken-, and inverted-gap materials. A quantitative understanding often necessitates a…
Period-doubling in the phase dynamics of a shunted HgTe quantum well Josephson junction
Wei Liu, Stanislau U. Piatrusha, Xianhu Liang +7
The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro…
Finite field transport response of a dilute magnetic topological insulator based Josephson junction
Pankaj Mandal, Nicolai Taufertshöfer, Lukas Lunczer +3
Hybrid samples combining superconductors with magnetic topological insulators are a promising platform for exploring exotic new transport physics. We examine a Josephson junction o…
Inhomogeneous superconductivity and quasilinear magnetoresistance at amorphous LaTiO3/SrTiO3 interfaces
N. Lebedev, M. Stehno, A. Rana +4
We have studied the transport properties of LaTiO3/SrTiO3 (LTO/STO) heterostructures. In spite of 2D growth observed in reflection high energy electron diffraction, Transmission El…
Gate-tunable transport properties of in-situ capped BiTe topological insulator thin films
Prosper Ngabonziza, Martin P. Stehno, Hiroaki Myoren +3
Combining the ability to prepare high-quality, intrinsic BiTe topological insulator thin films of low carrier density with in-situ protective capping, we demonstrate a pron…
