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…
