Abstract:
1. A method of manufacturing a crystal of a group III-V compound, the method comprising: a deposition step of depositing a metal film on a substrate; a heat-treatment step of heat-treating the metal film under an atmosphere in which a metal-film patterning compound is present so that the metal film becomes patterned with a plurality of grooves having an indefinite shape, the grooves having an average width of 2 nm to 5000 nm, the metal film having an aperture fraction of 5% to 80%, the aperture fraction being the percentage of the surface area that the grooves occupy with respect to the substrate total surface area; and a growth step of growing a group III-V crystal on the post-heat-treated metal film.
