Planar Josephson Junctions Templated by Nanowire Shadowing
P. Zhang, A. Zarassi, M. Pendharkar +16
More and more materials, with a growing variety of properties, are built into electronic devices. This is motivated both by increased device performance and by the studies of mater…
Large zero-bias peaks in InSb-Al hybrid semiconductor-superconductor nanowire devices
Hao Zhang, Michiel W. A. de Moor, Jouri D. S. Bommer +19
We report electron transport studies on InSb-Al hybrid semiconductor-superconductor nanowire devices. Tunnelling spectroscopy is used to measure the evolution of subgap states whil…
Strong Electron-Electron Interactions of a Tomonaga--Luttinger Liquid Observed in InAs Quantum Wires
Yosuke Sato, Sadashige Matsuo, Chen-Hsuan Hsu +12
We report strong electron-electron interactions in quantum wires etched from an InAs quantum well, a material known to have strong spin-orbit interactions. We find that the current…
Contribution of top barrier materials to high mobility in near-surface InAs quantum wells grown on GaSb(001)
Joon Sue Lee, Borzoyeh Shojaei, Mihir Pendharkar +3
Near-surface InAs two-dimensional electron gas (2DEG) systems have great potential for realizing networks of multiple Majorana zero modes towards a scalable topological quantum com…
Quantized Majorana conductance
Hao Zhang, Chun-Xiao Liu, Sasa Gazibegovic +19
Majorana zero-modes hold great promise for topological quantum computing. Tunnelling spectroscopy in electrical transport is the primary tool to identify the presence of Majorana z…
Transport studies of epi-Al/InAs 2DEG systems for required building-blocks in topological superconductor networks
Joon Sue Lee, Borzoyeh Shojaei, Mihir Pendharkar +7
One-dimensional (1D) electronic transport and induced superconductivity in semiconductor nano-structures are crucial ingredients to realize topological superconductivity. Our appro…
Epitaxy of Advanced Nanowire Quantum Devices
Sasa Gazibegovic, Diana Car, Hao Zhang +20
Semiconductor nanowires provide an ideal platform for various low-dimensional quantum devices. In particular, topological phases of matter hosting non-Abelian quasi-particles can e…
Proximity Effect Transfer from NbTi into a Semiconductor Heterostructure via Epitaxial Aluminum
A. C. C. Drachmann, H. J. Suominen, M. Kjaergaard +4
We demonstrate the transfer of the superconducting properties of NbTi---a large-gap high-critical-field superconductor---into an InAs heterostructure via a thin intermediate layer…
Gating of high-mobility InAs metamorphic heterostructures
J. Shabani, A. P. McFadden, B. Shojaei +1
We investigate the performance of gate-defined devices fabricated on high mobility InAs metamorphic heterostructures. We find that heterostructures capped with InGa$_{0.25…
