7 . the effect of the mqw on the hb - led is analyzed 全面分析多量子阱结构( mqw )在hb - led中的重要作用。
Mqw have the same effect on hb - led as dh , but better than that Mqw结构比dh结构更加有效的限制载流子,增加辐射复合效率。
Al content will decrease if using mqw even the same emitting wavelength . and it will improve the quality of the crystal 采用mqw结构可以减小相同发射波长下材料中的铝组分,从而改善了晶体大的质量。
And emission wavelength depends on ratio of well / barrier width more than number of wells . some useful data has been found through experiments 阱垒宽厚度比a较之mqw的周期数目n对pl发光波长的影响更大。
