Electronic and optical properties of core–shell InAlN nanorods: a comparative study via LDA, LDA-1/2, mBJ, HSE06, G0W0 and BSE methods

The DFT-based approaches LDA-1/2, mBJ, and HSE06 are valuable tools for investigating the electronic and optical properties of core–shell InAlN nanorods. They can approximate the state-of-the-art methods GW and BSE with much lower computational cost.
