    • A light-emitting element using GaN. On a substrate (10), formed are an SiN buffer layer (12), a GaN buffer layer (14), an undoped GaN layer (16), an Si-doped n-GaN layer (18), an SLS layer (20), an undoped GaN layer (22), an MQW light-emitting layer (24), an SLS layer (26), and a p-GaN layer (28), forming a p electrode (30) and an n electrode (32). The MQW light-emitting layer (24) has a structure in which InGaN well layers and AlGaN barrier layers are alternated. The Al content ratios of the SLS layers (20, and 26) are more than 5% and less than 24%. The In content ratio of the well layer in the MQW light-emitting layer (24) is more than 3% and less than 20%. The Al content ratio of the barrier layer is more than 1% and less than 30%. By adjusting the content ratio and film thickness of each layer to a desired value, the light luminous efficiency for wavelength of less than 400 nm is improved.
    • 使用GaN的发光元件。 在形成的衬底(10)上形成SiN缓冲层(12),GaN缓冲层(14),未掺杂的GaN层(16),Si掺杂的n-GaN层(18),SLS层(20 ),形成p型电极(30)和n电极(32)的未掺杂GaN层(22),MQW发光层(24),SLS层(26)和p-GaN层(28) 。 MQW发光层(24)具有其中InGaN阱层和AlGaN势垒层交替的结构。 SLS层(20和26)的Al含量比大于5%且小于24%。 MQW发光层(24)中的阱层的In含量比大于3%且小于20%。 阻挡层的Al含量比大于1%且小于30%。 通过将各层的含有率和膜厚度调整为所需值,波长小于400nm的光发光效率提高。
