    摘要: First, the substrate temperature is set to 1020° C., and an n-type cladding layer (14) made of n-type Al0.1Ga0.9N, an n-type optical guide layer (15) made of n-type GaN, and a flatness maintenance layer (16) made of n-type Al0.2Ga0.8N for maintaining the surface flatness of the n-type optical guide layer (15) by suppressing re-evaporation of the constituent atoms of the n-type optical guide layer (15), are grown in this order on a substrate (11) made of sapphire. Then, the supply of a group III material gas is stopped, the substrate temperature is decreased to 780° C., and the carrier gas is switched from a hydrogen gas to a nitrogen gas. Then, an active layer (17) having a multiple quantum well structure is grown by introducing NH3 as a group V source and selectively introducing TMI and TMG as a group III source.
