Abstract

The comparative study of ultrafast intersubband (IS) electron relaxation in GaN/AlGaN multiple quantum well (MQW) samples at different excitation powers and wavelengths was reported. All samples were grown by molecular beam epitaxy on sapphire substrates. IS lifetimes were measured using a time resolved pump-probe technique with pump and probe wavelengths between 1.5 and 1.75 μm.
