Figure 3From: Polarized photoreflectance and photoluminescence spectroscopy of InGaAs/GaAs quantum rods grown with As2 and As4 sourcesRoom temperature PPR and PPL spectra in the (001) plane for the As 2 -grown QR samples. (a) QR10, (b) QR20, and (c) QR35. PPL optical anisotropy of the GS interband transitions in the QRs is indicated by the DOP values.Back to article page
