Optical absorption on a single semiconductor
quantum dot with
a magnetic field applied in Voigt geometry |
The presented confocal setup in Voigt geometry
allows studying the anisotropic magnetic
properties of single self-assembled quantum dots with high
degree
of precision. The resonant optical
pumping
offers additionally a spin shelving scheme for the resident
electron in the QD. |

Tuning Fork based AFM Measurements of uncapped,
stacked InAs Quantum Dots in a GaAs matrix |
The sample under investigation features
stacked, uncapped InAs quantum dots in a GaAs matrix and has
been characterized via our Tuning Fork based AFM. For instance,
in the error image one can see atomic steps in the surrounding
InAs. |
