Journal ArticleDOI
Scaling of Majorana Zero-Bias Conductance Peaks.
Fabrizio Nichele,Asbjorn Drachmann,Alexander M. Whiticar,Eoin O'Farrell,Henri J. Suominen,Antonio Fornieri,Tian Wang,Geoffrey C. Gardner,Candice Thomas,Anthony Hatke,Peter Krogstrup,Michael J. Manfra,Karsten Flensberg,Charles Marcus +13 more
TL;DR: Results are consistent with theory, including a peak conductance that is proportional to tunnel coupling, saturates at 2e^{2}/h, decreases as expected with field-dependent gap, and collapses onto a simple scaling function in the dimensionless ratio of temperature and tunnel coupling.
Journal ArticleDOI
Two-dimensional epitaxial superconductor-semiconductor heterostructures: A platform for topological superconducting networks
Javad Shabani,Javad Shabani,Morten Kjaergaard,Henri J. Suominen,Younghyun Kim,Fabrizio Nichele,Kiryl Pakrouski,Tomaš Stankevič,Roman M. Lutchyn,Peter Krogstrup,Robert Feidenhans'l,S. Kraemer,Chetan Nayak,Matthias Troyer,Charles Marcus,Chris Palmstrom +15 more
TL;DR: In this article, a near perfect interface and a highly transparent contact can be achieved using epitaxial growth of aluminum on an InAs two-dimensional electron system, which satisfies all the requirements necessary to reach into the topological superconducting regime.
Journal ArticleDOI
Zero-Energy Modes from Coalescing Andreev States in a Two-Dimensional Semiconductor-Superconductor Hybrid Platform.
Henri J. Suominen,Morten Kjaergaard,Alex R. Hamilton,Alex R. Hamilton,Javad Shabani,Javad Shabani,Chris Palmstrom,Charles Marcus,Fabrizio Nichele +8 more
TL;DR: These measurements indicate a hard superconducting gap, ballistic tunneling contact, and in-plane critical fields up to 3 T in hybrid semiconductor-superconductor wires defined in a two-dimensional InAs/Al heterostructure using top-down lithography and gating.
Journal ArticleDOI
Quantized conductance doubling and hard gap in a two-dimensional semiconductor-superconductor heterostructure
Morten Kjaergaard,Fabrizio Nichele,Henri J. Suominen,Michał P. Nowak,Michael Wimmer,Anton R. Akhmerov,Joshua Folk,Karsten Flensberg,Javad Shabani,Chris Palmstrom,Charles Marcus +10 more
TL;DR: The hard-gap semiconductor–superconductor system demonstrated here is amenable to top-down processing and provides a new avenue towards low-dissipation electronics and topological quantum systems.
Journal ArticleDOI
Edge transport in the trivial phase of InAs/GaSb

TL;DR: In this article, transport and scanning measurements on InAs/GaSb double quantum wells are presented, where the top and back gates allow independent control of density and band offset, allowing tuning from the trivial to the topological regime.
