Description

Structure inversion asymmetry (SIA) related circular photogalvanic effect (CPGE) has been investigated under near-infrared radiation at temperatures ranging from 80 K to 290 K in GaAs/Al0.3Ga0.7As heterostructures. The result shows nonmonotonic changes of CPGE with temperature variation; obviously larger signal at low temperature and sign inversions in the temperature range between 140 K and 170 K are observed. We suggest this result is not only related to the photoconductivity and Rashba spin splitting, but other factors superpose on them.
