In this work we investigated ZnO films grown on semi-insulating (100) GaAs substrates by pulsed laser deposition. Samples were studied using techniques including X-ray diffraction (XRD), scanning electron microscopy, atomic force microscopy, Raman sp

We have determined the direct and exchange electron-electron and electron-hole Coulomb energies in CdSe/ZnSe quantum dots. The experiments are based on single dot photoluminescence at low temperature. By controlling the charging with a vertical trans

The effect of increasing annealing times on the emission energies and dot densities of ZnSe/CdSe quantum dots has been studied. Ensemble PL carried out at 77 K demonstrates the energy shift of the main peak attributed to fractional monolayer islands,

N-type doping of epitaxial ZnSe layers has been achieved using the thermal dissociation of silver iodide to generate molecular iodine. The source is stable under MBE conditions and reproducible doping levels ranging from 1016 to 1019 cm−3 were achi

By making use of epitaxial lift-off, ZnCdSe quantum wells are transferred onto a LiNbO3 substrate in order to employ its enhanced piezoelectric properties. The photoluminescence emission of this hybrid structure is characterized and the influence of

ZnO films were deposited on c-Al2O3 using pulsed laser deposition both with and without N2 in the growth ambient. X-ray diffraction revealed poorer crystal quality and surface morphology for one-step growths with N2 in the ambient. A marked improveme

We present key features of the strong coupling regime in a ZnSe-based microcavity; anticrossing with a normal mode splitting of 23.6 meV at 20 K; narrowing of the lower polariton linewidth near resonance; and composite evolution of the cavity-polarit

The stable crystal structure of magnesium sulfide (MgS) is rocksalt. However, the metastable zinc-blende structure is obtained when MgS is deposited by molecular beam epitaxy (MBE) on (001) zinc-blende substrates with a relatively small misfit. In th
