Effect of gallium termination on InGaAs wetting layer properties in droplet epitaxy InGaAs quantum dots
David Fricker, Paola Atkinson, Mihail I Lepsa +5
Self-assembled quantum dots based on III-V semiconductors have excellent properties for applications in quantum optics. However, the presence of a 2D wetting layer which forms duri…
Excitons in InGaAs Quantum Dots without Electron Wetting Layer States
Matthias C. Löbl, Sven Scholz, Immo Söllner +7
The Stranski-Krastanov (SK) growth-mode facilitates the self-assembly of quantum dots (QDs) using lattice-mismatched semiconductors, for instance InAs and GaAs. SK QDs are defect-f…
Direct imaging of a zero-field target skyrmion and its polarity switch in a chiral magnetic nanodisk
Fengshan Zheng, Hang Li, Shasha Wang +9
A target skyrmion is a flux-closed spin texture that has two-fold degeneracy and is promising as a binary state in next generation universal memories. Although its formation in nan…
Temperature and magnetic field dependence of the internal and lattice structures of skyrmions by off-axis electron holography
K. Shibata, A. Kovács, N. Kanazawa +2
The internal and lattice structures of magnetic skyrmions in B20-type FeGe are investigated using off-axis electron holography. The temperature, magnetic field and angular dependen…
