Figure 3From: Optical identification of electronic state levels of an asymmetric InAs/InGaAs/GaAs dot-in-well structure Photo-modulated reflectance of the as-grown sample measured at room temperature andthe shape fitting result of the complex QW-WL structure by the Aspnes formula (red solid line). Inset shows the schematic representation of band structure of an asymmetric dot-in-well QDs structure.Back to article page
