Highly transparent contacts to the 1D hole gas in ultra-scaled Ge/Si core/shell nanowires
Masiar Sistani, Jovian Delaforce, Roman Kramer +10
Semiconductor-superconductor hybrid systems have outstanding potential for emerging high-performance nanoelectronics and quantum devices. However, critical to their successful appl…
Scaling of sub-gap excitations in a superconductor-semiconductor nanowire quantum dot
Eduardo J. H. Lee, Xiaocheng Jiang, Rok Zitko +3
A quantum dot coupled to a superconducting contact provides a tunable artificial analogue of a magnetic atom in a superconductor, a paradigmatic quantum impurity problem. We realiz…
Zero-bias anomaly in a nanowire quantum dot coupled to superconductors
Eduardo J. H. Lee, Xiaocheng Jiang, Ramon Aguado +3
We studied the low-energy states of spin-1/2 quantum dots defined in InAs/InP nanowires and coupled to aluminium superconducting leads. By varying the superconducting gap, Δ, with…
Strong g-Factor Anisotropy in Hole Quantum Dots Defined in Ge/Si Nanowires
S. Roddaro, A. Fuhrer, C. Fasth +3
We demonstrate fully tunable single and double quantum dots in a one-dimensional hole system based on undoped Ge/Si core-shell nanowire heterostructures. The local hole density alo…
One-Dimensional Hole Gas in Germanium/Silicon Nanowire Heterostructures
Wei Lu, Jie Xiang, Brian P. Timko +2
Two-dimensional electron and hole gas systems, enabled through band structure design and epitaxial growth on planar substrates, have served as key platforms for fundamental condens…
Plastic Deformations in Mechanically Strained Single-Walled Carbon Nanotubes
D. Bozovic, M. Bockrath, J. H. Hafner +3
AFM manipulation was used to controllably stretch individual metallic single-walled carbon nanotubes (SWNTs). We have found that SWNTs can sustain elongations as great as 30% witho…
