Abstract:

After giving a brief introduction about the experimental techniques--- time resolved polarized photoluminescence (TRPPL) and time resolved Kerr rotation (TRKR), I will talk about our experimental results about the electron spin dynamics in low dimensional materials: spin dynamics in sub-monolayer InAs embedded in GaAs buffer, coherent spin transfer in a GaAs/InGaAs quantum well and electron spin lifetime in a high mobility, low density 2D electron gas. In the last case, experimental evidence was found to support Wu's prediction of the effect of the electron-electron scattering on electron spin dephasing.
