摘要
GaN/AlGaN multiple quantum wells with a subband spacing of similar to 740meV (lambda = 1.67 mum) have been studied. Using the time-resolved pump-and-probe technique, with 1.55 mum pump and 1.70 mum probe wavelength, the measurement of an intersubband electron scattering time of 370fs is reported.
