The atomic geometries, electronic structures, and formation energies of neutral nitrogen im- purities in ZnO have been investigated by first-principles calculations. The nitrogen impuri- ties are always deep acceptors...

We present a first-principles study on the geometric, vibrational and electronic properties of a novel Y-based non-scandium mixed-metal nitride clusterfullerene (TiY2N@C80). Theoretical results indicate that the fun...
First-principles calculations have been performed to clarify the differences of the electronic structures of Ga-doped ZnO and ZnS. Results show the local density approximation and local density approximation+U calcul...
