Measurement of spontaneous emission quantum efficiency in InGaAs/GaAs quantum wells
The spontaneous emission quantum efficiency of molecular beam epitaxy grown InGaAs/GaAs quantum wells is determined using photoluminescence measurements. The quantum efficiency is inferred from the power law that links pump power and integrated photoluminescence signal.
