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…
Materials considerations for forming the topological insulator phase in InAs/GaSb heterostructures
Borzoyeh Shojaei, Anthony P. McFadden, Mihir Pendharkar +3
In an ideal InAs/GaSb bilayer of appropriate dimension in-plane electron and hole bands overlap and hybridize, and a topologically non-trivial, or quantum spin Hall (QSH) insulator…
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…
