Abstract
Disclosed is a multi-quantum well structure including a stress relief layer, an electron-collecting layer disposed on the stress relief layer, and an active layer including a first active layer unit that is disposed on the electron-collecting layer. The first active layer unit includes potential barrier sub-layers and potential well sub-layers being alternately stacked, in which at least one of the potential barrier sub-layers has a GaN/AlInGaN stack, where 0<x1≤1 and 0≤y1<1. An LED device including the multi-quantum well structure is also disclosed.
