Figure 3From: Temperature and electron density dependence of spin relaxation in GaAs/AlGaAs quantum well Temperature dependence of electron spin relaxation times measured at excitation wavelength of 798 nm and optically pumped electron densities of 1.15 × 10 11 cm -2. (a) The time-resolved Kerr rotation signals measured at 20, 200, and 250 K for the asymmetric GaAs QW. (b) Temperature dependence of electron spin relaxation times measured for both symmetric and asymmetric GaAs QW samples. The solid lines are drawn to guide eyes.Back to article page
