<p>A substrate for forming a single-crystal thin film composed mainly of gallium nitride, indium nitride or aluminum nitride, the substrate comprising a sintered compact composed mainly of a ceramic material; and a thin-film substrate furnished with the single-crystal thin film. The use of the sintered compact composed mainly of a ceramic material, especially sintered compact with optical permeability, as the substrate enables formation thereon of a highly crystalline single-crystal thin film composed mainly of at least one selected from gallium nitride, indium nitride and aluminum nitride. Thus, there is provided a thin-film substrate furnished with a highly crystalline single-crystal thin film. Further, the use of the sintered compact composed mainly of a ceramic material enables providing of a light-emitting device excelling in luminous efficiency.</p> |
