Resumo |
Piezoelectric AlN layer grain orientation, grown by room temperature reactive sputtering, is analyzed by transmission electron microscopy (TEM).Two types of samples are studied: (i) AlN grown on well-polished NCD (nano-crystalline diamond) diamond, (ii) AlN grown on an up-side down NCD layer previously grown on a Si substrate, i.e. diamond surface as smooth as that of Si substrates. The second set of sample show a faster lignment of their AlN grain caxis attributed to it smoother diamond free surface. No grain orientation relationship between diamond substrate grain and the AlN ones is evidenced, which seems to indicate the preponderance role of the surface substrate state. |
