From: Temperature and electron density dependence of spin relaxation in GaAs/AlGaAs quantum well

Figure 3

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.
