Abstract

The effects of hydrogen implantation (Eion∼300 eV, dose∼4.4×1017 ions/cm2) on the optical properties of In0.053Ga0.947N0.017As 0.983/GaAs single quantum-wells are studied by spectroscopic ellipsometry and photoluminescence. A strong hydrogen-related blueshift of the quantum-well transition energy is observed by both techniques. After a thermal treatment at 300 °C, the original transition energy is nearly recovered. Optical constants of as-grown and implanted In0.053Ga 0.947N0.017As0.983 quantum-well layers are presented in the near-band gap spectral region (0.75-1.5 eV).
