摘要： The GaN facet growth method produces defect accumulating regions H on masks by forming a dotmask or a stripemask on an undersubstrate, growing GaN in a reaction furnace in vapor phase, inducing GaN crystals on exposed parts without covering the masks, inviting facets starting from verges of the masks and producing defect accumulating regions H on the mask. The defect accumulating regions H have four versions, that is, non (O), polycrystal (P), c-axis inclining single crystal (A) and orientation inversion (J). The best is the orientation inversion region (J). A sign of occurrence of the orientation inversion regions (J) is beaks of inversion orientation appearing on facets. GaN is grown on a masked undersubstrate by supplying a carbon material at a hydrocarbon partial pressure of 10 Pa to 5 kPa for 0.5 hour to 2 hour by an HVPE facet growth method without burying facets.

摘要： 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.
