Study of light efficiency and lifetime of LED with different surface structures
不同表面结构的半导体发光二极管的效率与寿命的研究

The main problem of GaAs based AlGaInP series LED is the low light extraction efficiency and heat generation inside,which have serious impact on the LED' lifetime. In this paper,we introduce a kind of LED with new surface structure formed of surface texture and light anti-reflecting layers through the post-epitaxial processing. In this new structure,the inside light transmission route has been changed and the current spreading is enhanced,which makes much more light emit outside. With the same injected curr...
