Microscopic origin of light emission in Al_yGa_{1-y}N/GaN superlattice: Band profile and active site

Duanjun Cai, Junyong Kang, Guang-Yu Guo

We present first-principles calculations of AlGaN/GaN superlattice, clarifying the microscopic origin of the light emission and revealing the effect of local polarization within th…
