Abstract:
A method for growing diamond crystals or cubic boron nitride crystals at a pressure and temperature within a diamond or cubic boron nitride stable region, which comprises:stacking a supporting layer and a raw material formed of non-diamond carbon species or low-pressure-phase boron nitride, placing a plurality of seed crystals such that the seed crystals come in contact with the supporting layer, wherein the seed crystals are placed in a regular pattern on a supporting plate or a raw material plate by placing the seed crystals on an adhesive sheet through pores formed in a regular pattern, transferring the regularly-placed seed crystals on the adhesive sheet onto the surface of the supporting plate or the raw material plate, and pressing the seed crystals against the surface; and the supporting plate or the raw material plate is used as the supporting layer or the raw material layer for growing the crystals.
