GaSb grown on GaAs substrates has been studied extensively in recent years for potential device applications. In this study, we have investigated the spin relaxation in GaSb with different thicknesses grown on GaAs substrates. The observed spin relaxation times are different at different thicknesses. This indicates that the crystal qualities affect the spin relaxation.
