Abstract:
1. A method for producing a single crystal by preferential epitaxial growth of {100} face, the method comprising the steps of: (1) growing in a growth direction a single crystal homoepitaxially on a first {100} face of a single crystal {100} substrate, the single crystal grown being the same material as the single crystal of the substrate; (2) cutting and polishing a side of the grown single crystal to form a surface parallel to a second {100} face of the single crystal {100} substrate; and (3) growing the crystal homoepitaxially on the surface parallel to the second {100} face of the single crystal {100} substrate, the single crystal grown being the same material as the single crystal {100} substrate, the steps (2) and (3) being performed once or more than once to form a single crystal grown on at least two surfaces in different directions.
