Hole-capture competition between a single quantum dot and an ionized acceptor
Julia Wiegand, Dmitry S. Smirnov, Jakob Osberghaus +3
We study the competition of hole capture between an In(Ga)As quantum dot and a directly adjacent ionized impurity in view of spin-photon interfaces. The Kerr rotation noise spectro…
Optical amplification of spin noise spectroscopy via homodyne detection
Pavel Sterin, Julia Wiegand, Jens Hübner +1
Spin noise (SN) spectroscopy measurements on delicate semiconductor spin systems, like single InGaAs quantum dots, are currently not limited by optical shot noise but rather by the…
Spin and reoccupation noise in a single quantum dot beyond the fluctuation-dissipation theorem
J. Wiegand, D. S. Smirnov, J. Hübner +2
We report on the nonequilibrium spin noise of a single InGaAs quantum dot charged by a single hole under strong driving by a linearly polarized probe light field. The spectral depe…
Molecular Packing Motifs Determine Charge-Transfer and Carrier Dynamics in Molecular Heterosystems: the Case of Pentacene - Perfluoropentacene
Andre Rinn, Tobias Breuer, Julia Wiegand +6
The great majority of electronic and optoelectronic devices depends on interfaces between n-type and p-type semiconductors. Finding such matching donor-acceptor systems in molecula…
Measurement of heavy-hole spin dephasing in (InGa)As quantum dots
R. Dahbashi, J. Hübner, F. Berski +5
We measure the spin dephasing of holes localized in self-assembled (InGa)As quantum dots by spin noise spectroscopy. The localized holes show a distinct hyperfine interaction with…
