    Bandgap Energies and Refractive Indices of Pb1-xSrxSe

    Optical transmission measurements were carried out on Pb1-xSrxSe samples with different Sr compositions (x ranging from 0 to 1) grown by molecular beam epitaxy (MBE). Refractive indices were calculated at room te...

    Photoluminescence study on coarsening of self-assembled InAlAs quantum dots on GaAs (001)

    Red-emission at ∼640 nm from self-assembled In0.55Al0.45As/Al0.5Ga0.5As quantum dots grown on GaAs substrate by molecular beam epitaxy (MBE) has been demonstrated. We obtained a double-peak structure of photolumi...
