Abstract
The present invention is intended to provide a semiconductor optoelectric device with high luminescent efficiency and a method of manufacturing the same. The semiconductor optoelectric device 18 according to the present invention is constructed by depositing compound-semiconductor layers 13 and 14 on a monocrystalline substrate 11 of a hexagonal close-packed structure. The shape of the monocrystalline substrate 11 is a parallelogram. Individual sides of the parallelogram are parallel to a <11-20> orientation. As the monocrystalline substrate, sapphire, zinc oxide or silicon carbide may be used. As the compound-semiconductor layers, an n-type GaN layer 13 and p-type GaN layer 14 may be used.
