Abstract
A method for forming a layer of monocrystalline diamond cubic material on a mask comprises initially providing a substrate having a monocrystalline surface which is parallel to a {100}-type crystallographic plane. A mask is then formed on the substrate, the mask including at least two apertures and each aperture including an edge which is oriented between 8.degree. and 14.degree. from a particular <001> direction on the surface. The aperture edges are mutually parallel and in mutual opposition and the mask apertures each expose a monocrystalline surface portion of the substrate. The diamond cubic material is then epitaxially grown through the apertures and over the mask so as to form a monocrystalline layer of substantially uniform quality overlying the mask between the edges of the apertures.
