InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Selective Area Growth Rates of III-V Nanowires
Martin Espiñeira Cachaza, Anna Wulff Christensen, Daria Beznasyuk +6
Selective area growth (SAG) of semiconductors is a scalable method for fabricating gate-controlled quantum platforms. This letter reports on the adatom diffusion, incorporation, an…
Tuning Yu-Shiba-Rusinov States in a Quantum Dot
Anders Jellinggaard, Kasper Grove-Rasmussen, Morten Hannibal Madsen +1
We present transport spectroscopy of sub-gap states in a bottom gated InAs nanowire coupled to a normal lead and a superconducting aluminium lead. The device shows clearly resolved…
Exponential Protection of Zero Modes in Majorana Islands
S. M. Albrecht, A. P. Higginbotham, M. Madsen +5
Majorana zero modes are quasiparticle excitations in condensed matter systems that have been proposed as building blocks of fault-tolerant quantum computers [1]. They are expected…
Electrical tuning of Rashba spin-orbit interaction in multigated InAs nanowires
Zoltán Scherübl, Gergő Fülöp, Morten Hannibal Madsen +2
Indium arsenide (InAs) nanowires (NWs) are a promising platform to fabricate quantum electronic devices, among others they have strong spin-orbit interaction (SOI). The controlled…
Alignment free characterization of 2D gratings
Morten Hannibal Madsen, Pierre Boher, Poul-Erik Hansen +1
Fast characterization of 2-dimensional gratings is demonstrated using a Fourier lens optical system and a differential optimization algorithm. It is shown that both the grating spe…
