Spectral shadows of a single GaAs quantum dot
Kai Hühn, Lena Klar, Fei Ding +4
Semiconductor quantum dots are a promising platform for generating single and entangled photons.Still, their use is limited even in the most advanced structures by changes in the c…
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…
Surface quantum dots with pure, coherent, and blinking-free single photon emission
Xin Cao, Jingzhong Yang, Pengji Li +14
The surface of semiconductor nanostructures has a major impact on their electronic and optical properties. Disorder and defects in the surface layer typically cause degradation of…
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…
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…
