Determination of the direct band-gap energy of InAlAs matched to InP by photoluminescence excitation spectroscopy
A series of InxAl1-xAs samples (0.51≪x≪0.55)coherently grown on InP was studied in order to measure the band-gap energy of the lattice matched composition. As the substrate is opaque to the relevant photon energies, a method is developed to calculate the optical absorption coefficient from the photo...
