Two-way photoeffect-like occupancy dynamics in a single (InGa)As quantum dot
Pavel Sterin, Kai Hühn, Jens Hübner +1
We extend optical spin noise spectroscopy on single (InGa)As quantum dots to high magnetic fields at which the splitting between the two optical active Zeeman branches of the posit…
Room Temperature Micro-Photoluminescence Studies of Colloidal WS2 Nanosheets
André Philipp Frauendorf, André Niebur, Lena Harms +5
Wet-chemical syntheses for quasi two-dimensional (2D) transition metal dichalcogenides (TMDs) have emerged as promising methods for straightforward solution-processing of these mat…
Low Temperature Relaxation of Donor Bound Electron Spins in Si:P
Eduard Sauter, Nikolay V. Abrosimov, Jens Hübner +1
We measure the spin-lattice relaxation of donor bound electrons in ultrapure, isotopically enriched, phosphorus-doped Si:P. The optical pump-probe experiments reveal at low…
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…
Closing the gap between spatial and spin dynamics of electrons at the metal-to-insulator transition
J. G. Lonnemann, E. P. Rugeramigabo, M. Oestreich +1
We combine extensive precision measurements of the optically detected spin dynamics and magneto-transport measurements in a contiguous set of n-doped bulk GaAs structures in order…
