英文摘要
Spin-orbit interaction (SOI) plays important roles in the field of spintronics because the SOI field enables for spin manipulation and causes spin relaxation. In this study, using time-resolved Kerr rotation measurement, we investigate ensemble spin dynamics in wires made from a modulation-doped AlGaAs/GaAs QW in which both Dresselhaus and Rashba SOIs coexist. In addition, we perform the time- and spatially-resolved Kerr rotation measurement to observe the spatiotemporal evolution of photoexcited spins, and demonstrated gate-controlled spin distribution of a two-dimensional electron gas with a top gate electrode.
