摘要 | PURPOSE:To perform a high intensity light emitting element having a visible short wavelength (blue-ultraviolet) light by forming a semiconductor substrate of compound semiconductor and a current injection part of compound semiconductor containing at least Be and Te as component elements. CONSTITUTION:A semiconductor substrate 1 is formed of compound semiconductor, and a current injection part 2 is formed of compound semiconductor containing at least Be (beryllium) and Te (tellurium) as component elements. In this case, since characteristic containing conductivity of the current injection layer 2 relatively scarcely depending upon a defect in an epitaxially grown layer, desired (low resistance, etc.) characteristic can be easily obtained, and the band gap of the layer 2 is sufficiently larger than that of the light emitting layer 1 without respect to light emitting characteristic, but its band gap can be increased larger than that of the layer Thus, an injection efficiency can be greatly improved. Thus, a light emitting element having a high intensity blue light emitting diode can be manufactured. |
其他摘要 | 目的:通过形成化合物半导体的半导体衬底和至少含有Be和Te作为组分元素的化合物半导体的电流注入部分,来执行具有可见短波长(蓝 - 紫外)光的高强度发光元件。组成:半导体衬底1由化合物半导体形成,电流注入部分2由至少含有Be(铍)和Te(碲)作为组成元素的化合物半导体形成。在这种情况下,由于电流注入层2的导电性的特性相对几乎不依赖于外延生长层中的缺陷,因此可以容易地获得所需的(低电阻等)特性,并且层2的带隙足够在不考虑发光特性的情况下,其发光层的间隙可以大于发光层1,但是其带隙可以比层1的带隙大。这样,可以大大提高注入效率。因此,可以制造具有高强度蓝色发光二极管的发光元件。 |
