Experimental investigation of the optical spin selection rules in bulk Si and Ge/Si quantum dots
N. Sircar, D. Bougeard
We study the relationship between the circular polarization of photoluminescence and the magnetic field-induced spin-polarization of the recombining charge carriers in bulk Si and…
Quantum Hall Resistance Overshoot in 2-Dimensional Electron Gases - Theory and Experiment
J. Sailer, A. Wild, V. Lang +2
We present a systematical experimental investigation of an unusual transport phenomenon observed in two dimensional electron gases in Si/SiGe heterostructures under integer quantum…
Electrostatically defined Quantum Dots in a Si/SiGe Heterostructure
A. Wild, J. Sailer, J. Nützel +3
We present an electrostatically defined few-electron double quantum dot (QD) realized in a molecular beam epitaxy grown Si/SiGe heterostructure. Transport and charge spectroscopy w…
Enhanced photoluminescence emission from two-dimensional silicon photonic crystal nanocavities
N. Hauke, T. Zabel, K. Mueller +6
We present a temperature dependent photoluminescence study of silicon optical nanocavities formed by introducing point defects into two-dimensional photonic crystals. In addition t…
A Schottky top-gated two-dimensional electron system in a nuclear spin free Si/SiGe heterostructure
J. Sailer, V. Lang, G. Abstreiter +8
We report on the realization and top-gating of a two-dimensional electron system in a nuclear spin free environment using 28Si and 70Ge source material in molecular beam epitaxy. E…
