Transport spectroscopy of induced superconductivity in the three-dimensional topological insulator HgTe
Jonas Wiedenmann, Eva Liebhaber, Johannes Kübert +6
The proximity-induced superconducting state in the 3-dimensional topological insulator HgTe has been studied using electronic transport of a normal metal-superconducting point cont…
Phase-sensitive SQUIDs based on the 3D topological insulator HgTe
Luis Maier, Erwann Bocquillon, Manuel Grimm +6
Three-dimensional topological insulators represent a new class of materials in which transport is governed by Dirac surface states while the bulk remains insulating. Due to helical…
-periodic Josephson supercurrent in HgTe-based topological Josephson junctions
Jonas Wiedenmann, Erwann Bocquillon, Russell S. Deacon +12
The Josephson effect describes the generic appearance of a supercurrent in a weak link between two superconductors. Its exact physical nature however deeply influences the properti…
Thermal Gating of Charge Currents with Coulomb Coupled Quantum Dots
Holger Thierschmann, Fabian Arnold, Marcel Mittermüller +5
We have observed thermal gating, i.e. electrostatic gating induced by hot electrons. The effect occurs in a device consisting of two capacitively coupled quantum dots. The double d…
Non-sinusoidal current-phase relationship in Josephson junctions from the 3D topological insulator HgTe
Ilya Sochnikov, Luis Maier, Christopher A. Watson +8
We use Superconducting QUantum Interference Device (SQUID) microscopy to characterize the current-phase relation (CPR) of Josephson Junctions from 3-dimentional topological insulat…
Josephson supercurrent through the topological surface states of strained bulk HgTe
Jeroen B. Oostinga, Luis Maier, Peter Schueffelgen +6
Strained bulk HgTe is a three-dimensional topological insulator, whose surface electrons have a high mobility (30,000 cm^2/Vs), while its bulk is effectively free of mobile charge…
