First-principles investigation of the vacancy effect on the electronic properties in M2AlC(M = V and Nb)

Autor: Liu Kun, Qi Yuan, Duan Ji-Zheng

Publikováno v: AIP Advances, Vol 4, Iss 10, Pp 107137-107137-7 (2014)

First principles calculations have been performed to study the mono-vacancy formation energies and electronic properties of M2AlC (M = V and Nb) compound. The results show that the M mono-vacancy has a maximum formation energy. While the C mono-vacan
