Quantum-dot thermometry
E. A. Hoffmann, N. Nakpathomkun, A. I. Persson +3
We present a method for the measurement of a temperature differential across a single quantum dot that has transmission resonances that are separated in energy by much more than th…
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…
Direct Measurement of the Spin-Orbit Interaction in a Two-Electron InAs Nanowire Quantum Dot
C. Fasth, A. Fuhrer, L. Samuelson +2
We demonstrate control of the electron number down to the last electron in tunable few-electron quantum dots defined in catalytically grown InAs nanowires. Using low temperature tr…
Fabrication, optical characterization and modeling of strained core-shell nanowires
Z. Zanolli, L. E. Froeberg, M. T. Bjoerk +2
Strained nanowires with varying InAs/InP core-shell thicknesses were grown using Chemical Beam Epitaxy. Microphotoluminescence spectroscopy, performed at low temperature, was then…
Quantum confinement effects in InAs-InP core-shell nanowires
Z Zanolli, M-E Pistol, L E Froeberg +1
We report the detection of quantum confinement in single InAs-InP core-shell nanowires. The wires having an InAs core with ~25 nm diameter are characterized by emission spectra in…
