The density functional theory calculations using general gradient approximation (GGA) have been systematically performed to study the electronic structures, the density of states (DOS), and magnetic properties of V-doped GaN nanosheet for different dopant concentrations (2.08% and 4.16%). We conducted the entire study using the Atomistix ToolKit code. The electronic properties were improved with the Hubbard values U = 4 eV. V-doped CaN nanosheet exhibits stable ferromagnetic (FM) states relative to corresponding antiferromagnetic (AFM) states. The calculated TC with the V-doping is found to be above the room temperature (RT) one. Calculation results reveal that V-doped nanosheets may be good candidates for spintronics due to their good half-metal ferromagnetism.
