Fig. 4From: Telecommunication Wavelength-Band Single-Photon Emission from Single Large InAs Quantum Dots Nucleated on Low-Density Seed Quantum Dots a Excitation power-dependent μPL spectra of sample A at 10 K. X neutral exciton line, X* charged one. b Power dependence of the intensity of exciton lines X (square) and X* (circles). Colored lines: linear fitting, showing different slopes. c Time-resolved μPL intensity of X line, red: exponential decay fittingBack to article page
