Figure 4From: Raman scattering of InAs/AlAs quantum dot superlattices grown on (001) and (311)B GaAs surfacesRaman spectra of samples B 001 and B 113 (blue and red curves, respectively). Measured in the spectral ranges of (a) InAs measured in both polarized and depolarized (thin lines) geometries and (b) AlAs optical phonons measured in the polarized geometry with different excitation wavelengths.Back to article page
