Nonlinear effects in spin relaxation of cavity polaritons
D. D. Solnyshkov, I. A. Shelykh, M. M. Glazov +5
We present the general kinetic formalism for the description of spin and energy relaxation of the cavity polaritons in the framework of the Born-Markov approximation. All essential…
Electrical spin injection into p-doped quantum dots through a tunnel barrier
L. Lombez, P. Renucci, P. Gallo +14
We have demonstrated by electroluminescence the injection of spin polarized electrons through Co/Al2O3/GaAs tunnel barrier into p-doped InAs/GaAs quantum dots embedded in a PIN GaA…
Bistability of the Nuclear Polarisation created through optical pumping in InGaAs Quantum Dots
P. -F. Braun, B. Urbaszek, T. Amand +5
We show that optical pumping of electron spins in individual InGaAs quantum dots leads to strong nuclear polarisation that we measure via the Overhauser shift (OHS) in magneto-phot…
