Magneto-optical properties of charged excitons in quantum dots
A. O. Govorov, C. Schulhauser, D. Haft +7
We present both experimental and theoretical results on the influence of a magnetic field on excitons in semiconductor quantum dots. We find a pronounced difference between the str…
Transport signatures of correlated disorder in a two-dimensional electron gas
T. Heinzel, R. D. Jaeggi, E. Ribeiro +5
We report electronic transport measurements on two-dimensional electron gases in a Ga[Al]As heterostructure with an embedded layer of InAs self-assembled quantum dots. At high InAs…
Single-electron charging of self-assembled InAs quantum dots
M. Fricke, A. Lorke, M. Haslinger +3
The many-particle ground state and excitations of self-assembled InAs quantum dots are investigated using far-infrared (FIR) and capacitance spectroscopy. The contributions of quan…
Far-infrared and capacitance spectroscopy of self-assembled InAs quantum dots
A. Lorke, M. Fricke, B. T. Miller +4
We review a number of recent experiments which are probing ground state and excitations of few-electron systems in self-assembled InAs quantum dots. Far-infrared spectroscopy, toge…
