Optical and electrical quality of InGaP grown on GaAs with low pressure metalorganic chemical vapour deposition

Mg-doped AlGaN grown on an AlN/sapphire template by metalorganic chemical vapour deposition

The growth of high-performance Mg-doped p-type Al x Ga1–xN (x = 0.35) layers using low-pressure metalorganic chemical vapour deposition on an AlN/sapphire template is reported. The influence of growth conditions on the p-type conductivity of the Al x Ga1–xN (x = 0.35) alloy was investigated. It was found that the p-type resistivity of the AlGaN alloy demonstrates a marked dependence on the Mg c...

Photoluminescence investigation of GaN films grown by metalorganic chemical vapor deposition on (100) GaAs

GaN films were grown on (100) GaAs substrates by metalorganic chemical vapor deposition and were found to be of (200) cubic or (111) cubit/(0002) hexagonal phase. Their photoluminescence characteristics remained invariant with material phase. We report assignment of band-edge photoluminescence near 3!36 eV and 3.15-3.31 eV in apparently cubic GaN to intrinsic/bound excitons and phonon-assisted,...

Optical and transport properties of InSb thin films grown on GaAs by metalorganic chemical vapor deposition

Optical and transport properties of InSb thin films grown on GaAs by metalorganic chemical vapor deposition (MOCVD) have been investigated by far-infrared (FIR) reflectance spectroscopy. The lattice vibration behaviors of a series of MOCVD InSb/GaAs(100) materials grown under different growth conditions were studied. Effects of III–V source ratios on the films crystalline quality were examined....

Ferroelectric PbTiO3 films grown by pulsed liquid injection metalorganic chemical vapour deposition

The influence of various deposition conditions (deposition temperature, partial oxygen pressure and solution composition) to the growth of ferroelectric PbTiO3 (PTO) films by pulsed liquid injection metalorganic chemical vapour deposition (MOCVD) was examined. Films were grown on LaAlO3 (001), SrTiO3 (001) and sapphire (R-plane) substrates. Pb(thd)2 and Ti(O i Pr)2(thd)2 (thd = 2,2,6,6-tetramet...
