Figure 3From: Spin photocurrent spectra induced by Rashba- and Dresselhaus-type circular photogalvanic effect at inter-band excitation in InGaAs/GaAs/AlGaAs step quantum wellsThe magnitude of CPGE current as a function of angle of incidence. The squares and circles symbols indicate the CPGE current of the excitonic state 1H1E induced by SIA and BIA, respectively. The solid lines are the fitting results.Back to article page
