g-factor engineering and control in self-assembled quantum dots
G. Medeiros-Ribeiro, E. Ribeiro, H. Westfahl
The knowledge of electron and hole g-factors, their control and engineering are key for the usage of the spin degree of freedom for information processing in solid state systems. T…
Aharonov-Bohm signature for neutral excitons in type-II quantum dot ensembles
E. Ribeiro, G. Medeiros-Ribeiro, W. Carvalho +1
It is commonly believed that the Aharonov-Bohm (AB) effect is a typical feature of the motion of a charged particle interacting with the electromagnetic vector potential. Here we p…
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…
Metal-Insulator Transition in a Disordered Two-Dimensional Electron Gas in GaAs-AlGaAs at zero Magnetic Field
E. Ribeiro, R. Jaeggi, T. Heinzel +3
A metal-insulator transition in two-dimensional electron gases at B=0 is found in Ga(Al)As heterostructures, where a high density of self-assembled InAs quantum dots is incorporate…
