Fig. 3From: Electronic Coupling in Nanoscale InAs/GaAs Quantum Dot Pairs Separated by a Thin Ga(Al)As SpacerLow-temperature PL spectra of (a) sample A and (b) sample B as a function of the excitation laser intensity. The insets show the PL intensity ratio R of the E 1 emission to the E 0 emission (R = E 1 emission/E 0 emission × 100 %) as a function of the excitation laser intensityBack to article page
