| Abstract | The influence of deposition temperature on phase formation of V(2)AlC is studied by magnetron sputtering from elemental targets. At substrate temperatures below 750 degrees C, we observed the formation of Al(x)V(y) and V(2)C using x-ray diffraction (XRD) analysis. At 750 degrees C, a phase pure polycrystalline V(2)AlC film on a similar to 12 nm thick transition layer has been observed using XRD and transmission electron microscopy. Selected area electron diffraction indicates that the film grown on the transition layer consists of phase pure V(2)AlC. As the substrate temperature is increased to 850 degrees C, the formation of V(2)C in addition to the V(2)AlC phase is observed. This may be due to desorption of aluminium causing the decomposition of V(2)AlC into vanadium carbides and aluminium. The V(2)AlC film is fully dense and polycrystalline and the elastic modulus based on nanoindentation is within the expected error margin consistent with previously reported theoretical calculations and the diamond anvil cell measurement of bulk V(2)AlC samples. |
