    Growth of (100) oriented diamond grains by the application of lateral temperature gradients across silicon substrates

    Polycrystalline diamond films with a predominant (100) texture were deposited onto silicon substrates using hot-filament chemical vapor deposition. During film deposition, different temperature gradients were ...
