What is it about?
In summary, we have presented the results of (Density Functional Theory) DFT calculations to investigate the stability, structural, electronic, and optical properties of two-dimensional graphene-like g-GaN. This work is inspired from one of my colleagues who studied his/her PhD thesis in III-N materials back in Manchester, UK.

Why is it important?
The Kohn-Sham bandstructure, optical spectra and elastic constants at (Heyd-Scuseria-Ernzerhof) HSE03 level provide more accurate estimates on the nature and the value of the main bandgap, absorption onsets, and other mechanical properties in comparison with “pure” exchange-correlation functionals.
Perspectives
Overall, one can say that the two-dimensional g-GaN have more intense optical activity in the (vacuum ultra-violet) VUV range. We believe that the diverse and interesting properties exhibited by the g-GaN material in this theoretical study will stimulate research, leading eventually to their synthesis and applications.
