Growth and Strain Relaxation Mechanisms of InAs/InP/GaAsSb Core-Dual-Shell Nanowires
Omer Arif, Valentina Zannier, Ang Li +4
The combination of core/shell geometry and band gap engineering in nanowire heterostructures can be employed to realize systems with novel transport and optical properties. Here, w…
Anisotropies of the g-factor tensor and diamagnetic coefficient in crystal-phase quantum dots in InP nanowires
Shiyao Wu, Kai Peng, Sergio Battiato +17
Crystal-phase low-dimensional structures offer great potential for the implementation of photonic devices of interest for quantum information processing. In this context, unveiling…
Multiple Andreev reflections and Shapiro steps in a Ge-Si nanowire Josephson junction
Joost Ridderbos, Matthias Brauns, Ang Li +4
We present a Josephson junction based on a Ge-Si core-shell nanowire with transparent superconducting Al contacts, a building block which could be of considerable interest for inve…
Hard superconducting gap and diffusion-induced superconductors in Ge-Si nanowires
Joost Ridderbos, Matthias Brauns, Jie Shen +8
We show a hard induced superconducting gap in a Ge-Si nanowire Josephson transistor up to in-plane magnetic fields of mT, an important step towards creating and detecting Maj…
Kinetic Control of Morphology and Composition in Ge/GeSn Core/Shell Nanowires
Simone Assali, Roberto Bergamaschini, Emilio Scalise +8
The growth of Sn-rich group-IV semiconductors at the nanoscale provides new paths for understanding the fundamental properties of metastable GeSn alloys. Here, we demonstrate the e…
Josephson effect in a few-hole quantum dot
Joost Ridderbos, Matthias Brauns, Jie Shen +5
We use a Ge-Si core-shell nanowire to realise a Josephson field-effect transistor with highly transparent contacts to superconducting leads. By changing the electric field we gain…
Spin-orbit interaction and induced superconductivity in an one-dimensional hole gas
F. K. de Vries, J. Shen, R. J. Skolasinski +11
Low dimensional semiconducting structures with strong spin-orbit interaction (SOI) and induced superconductivity attracted much interest in the search for topological superconducto…
Highly tuneable hole quantum dots in Ge-Si core-shell nanowires
Matthias Brauns, Joost Ridderbos, Ang Li +3
We define single quantum dots of lengths varying from 60 nm up to nearly half a micron in Ge-Si core-shell nanowires. The charging energies scale inversely with the quantum dot len…
Anisotropic Pauli spin blockade in hole quantum dots
Matthias Brauns, Joost Ridderbos, Ang Li +3
We present measurements on gate-defined double quantum dots in Ge-Si core-shell nanowires, which we tune to a regime with visible shell filling in both dots. We observe a Pauli spi…
Electronic Band Structure of Wurtzite GaP Nanowires via Resonance Raman Spectroscopy
Jaya Kumar Panda, Anushree Roy, Mauro Gemmi +4
Raman measurements are performed on defect-free wurzite GaP nanowires. Resonance Raman measurements are carried out over the excitation energy range between 2.19 and 2.71 eV. Reson…
