Abstract

The behavior of Mg dopants in InN films grown by molecular beam epitaxy was studied by Raman scattering in a wide Mg concentration ([Mg]) range from 1 × 10¹⁶ to 4 × 10²¹ cm⁻³. Transition of dominant lattice sites of Mg dopants was investigated through a diffusion-collision model based on Mg-related local vibrational modes, which was further confirmed through stress analysis. It was found that Mg_i and Mg_In-N-In_i are the dominant sites of Mg dopants at [Mg] < 1.8 × 10²⁰ cm⁻³, while the complex of Mg_In-N-Mg_i dominates with further increasing [Mg]. This study provides an insight on the behavior of Mg and would be helpful for achieving effective p-type doping in InN.
