Abstract :
We report first applications of pump-probe second harmonic generation (SHG) to monitor spin dynamics in nonmagnetic semiconductor heterostructures (GaAs/GaSb and GaAs/GaSb/InAs). We also examine the band offsets of InAs/CdMnSe samples using internal photoemission and second harmonic generation
