Cathodoluminescence of zinc sulfide films grown by single source chemical vapor deposition

Article Abstract:

The cathodoluminescent properties of zinc sulfide (ZnS) films prepared via single-source chemical vapor deposition of zinc dimethyldithiocarbonate under a variety of precursor fluxes were examined. The results suggest that ZnS thin films grown using a low cost and straightforward technique such as a single-source chemical vapor deposition may have potential applications in producing light-emitting devices.

Structural order in oxygenated gallium nitride films

Article Abstract:

Structural order in nanocrystalline, oxygenated GaN thin films (thickness ~ 500 nm) has been examined. The results of angle-dependent near-edge X-ray absorption fine structure facilitated the formation of a short-range structural model, which explained the influences of the oxygen concentration on the long-range order in the films.

Fe/Co alloys for the catalytic chemical vapor deposition synthesis of single- and double-walled carbon nanotubes (CNTs). 1. The CNT-Fe/Co-MgO system

Article Abstract:

A detailed investigation of the Fe/Co alloys' formation and composition is reported. It appears that the presence of Co(super +2) ions hinders the dissolution of iron in the MgO lattice, so that an increasing fraction of cobalt in the oxide powders favors the formation and clustering of Fe(super 3+) ions.
