Notes:
The optical spectra of a molecular-beam-epitaxially grown In0.53Ga0.47As epilayer lattice-matched on a (100) InP substrate are measured in the visible and infrared regions. The transmittance, reflectance, and their wavelength derivatives (wavelength-modulation spectra) are measured at room temperature. The spectra were analyzed by a theoretical spectral line-shape calculation based upon the band structure near the fundamental band gap. The quasidielectric functions and optical constants in the 0.6–3.1 eV range and the critical energies E0, E0+Δ0, E1, and E1+Δ1 are determined by fitting the calculated spectral line shapes to the measured spectra.
