We present a unified picture of our studies of the nitrogen-specific properties of InGaAsN. Nitrogen-induced bandgap reduction and symmetry-breaking are examined with band-structure calculations and pressure-dependent optical measurements for an idea

Photoluminescence measurements in a magnetic field between 0 and 13.6 T were carried out on CuPtB-ordered GaInP at liquid-helium temperature. Four samples of different degrees of ordering (η, varying from 0 to 0.54) were studied. Experimental result

We report a measurement of the variation of the diamagnetic shift of a heavy-hole exciton in a single coherently strained GaAs0.685Sb0.3N0.015/GaAs quantum well as a function of magnetic field up to 32 T at 1.3 K using photoluminescence spectroscopy.

We present the optical and structural characterization of a two-dimensional array of self-organized AlInAs quantum wires. The structure was created by epitaxially stacking along the [001] direction thin self-assembled, [100]-oriented, superlattices s

To gain insight into the nitrogen-related defects of InGaAsN, nitrogen vibrational mode spectra, Hall mobilities, and minority carrier diffusion lengths are examined for InGaAsN (1.1 eV band gap) grown by molecular beam epitaxy (MBE). Annealing promo

Growth of InAs/AlAs short-period superlattices on appropriately miscut (001) InP substrates is shown to alter the microstructure of composition modulation from a 2D organization of short compositionally enriched wires to a single dominant modulation

Time-resolved photoluminescence spectroscopy has been used to investigate carrier decay dynamics in a InxGa1−xAs1−yNy (x∼0.03, y∼0.01) epilayer grown on GaAs by metal organic chemical vapor deposition. Time-resolved photoluminescence (PL) mea
