What is it about?
265 nm LED is controlled by the edgeline. However, both edgeline and terraces emits light for the case of 285 nm LED.

Why is it important?
Effective diffusion length dependency on Ga content is key parameter for this phenomenon.
Perspectives
Improving LEDs > 280 nm and <270nm is essentially different.
