Mos2 Monolayer

From first-principles calculations, Cr/Fe δ-type doping effectively modulates electronic and magnetic properties of monolayer MoS2. Compared with ferromagnetic half-metallic Fe δ-type doped MoS2, Cr and Fe alternately δ-type codoped MoS2 is ferrimagnetic and half-metallic.

Nb Doping

In this work, the electronic and magnetic properties of Nb-doped full-Huesler alloy Ti2NiAl with Hg2CuTi-type structure have been investigated by using first-principles calculations within the density function theory (DFT). Due to the Nb which has less valence electrons than Ni doping into Ni-site, the gap around the Fermi level of the compound Ti2Ni1-xNbxAl (0≤x≤1) is gradually narrowed, and destroyed completely as x≥0.5. With the increase of x, it has gone through the transition from the ferromagnetism to the non-magnetism, and then to the ferromagnetism finally. Further analyses of density of states reveal that the d-electronic rehybridization induced by Nb-doping and RKKY-type indirect interaction is directly responsible for the changes of half-metallicity and magnetism.

The electronic and magnetic properties of IIIA group doped ZnO nanosheets (ZnONSs) are investigated by the first principles. The results show that the band gap of ZnO nanosheets increases gradually along with Al, Ga, and In ions occupying Zn sites and O sites. The configuration of Al atoms replacing Zn atoms is more stable than other doped. The system shows half-metallic characteristics for In-doped ZnO nanosheets.
