摘要:
A GaN crystal substrate has a crystal growth surface on which a crystal is grown, and a rear surface opposite to the crystal growth surface. The crystal growth surface has a roughness Ra(C)of at most 10 nm, and the rear surface has a roughness Ra(R) of at least 0.5 μand at most 10 μm. A ratio Ra(R)/Ra(C) of the surface roughness Ra(R) to the surface roughness Ra(C) is at least 50. Thus, a GaN crystal substrate of which front and rear surfaces are distinguishable from each other is provided, without impairing the morphology of a semiconductor layer grown on the GaN crystal substrate.

An apparatus for converting optical information into an electrical information signal includes a plurality of one-dimensional conversion arrays arranged in parallel form. Each one-dimensional conversion array has first and second photoelectric conversion structures integrally formed. The first photoelectric conversion structure has photoelectric conversion elements each having a light receiving surface onto which an information light is projected. The second photoelectric conversion structure has photoelectric conversion elements each having a sweep light receiving surface onto which a sweep light is projected. The sweep light has a cross section which simultaneously scans the sweep light receiving surface of one of the photoelectric conversion elements included in each of the one-dimensional conversion arrays. The electrical information signal is read out from the photoelectric conversion elements provided in the first photoelectric conversion structure when the sweep light is projected onto the photoelectric conversion elements provided in the second photoelectric conversion structure.
