abstract = "This study reports a high light extraction efficiency (LEE) light emitting diode (LED) by harnessing asymmetric obtuse angle micro-structured roofs. In comparison to conventional symmetric micro-structured roofs, the LEE has been improved from 62% to 73%. This represents an 11% improvement in LEE, which is significant for LED. It is speculated that this improvement is largely due to the increased surface area and better randomization on the direction of transmitted/reflected light, which enhances the escaping probability after multiple reflections.",
