| Popis: | We report the thin film deposition of copper iodide with zincblende type structure (γ-CuI) via metal-organic chemical vapor deposition (MOCVD). Single crystals and thin films of Cu and γ-CuI could be formed on various substrates from cyclopentadienylcopper triethylphosphine (CpCuPEt 3 ) and ethyliodide (C 2 H 5 I) as precursors for copper and iodine, respectively. Additionally, the chemical reaction behavior of thermally evaporated and MOCVD deposited elemental copper films with C 2 H 5 I is examined. SiO 2 glass and various single crystalline oxides and semiconductors were used as substrates. For all cases X-ray diffraction measurements revealed polycrystalline γ-CuI with zincblende type structure; other CuI phases could not be detected. Photoluminescence measurements show a broadened peak at 420 nm due to donor-acceptor pair recombination. Intense peaks at shorter wavelengths are attributed to excitonic emissions. |
