Half-metallic ferromagnetism in transition-metal doped germanium nitride: A first-principles study
Sheng-Li Zhang, Wei Wang, Er-Hu Zhang
The electronic and magnetic properties of transition-metal doped -Ge3N4 have been studied using first-principles calculations. The results show that the substitutional transitio…
The Modulation of de Haas-van Alphen Effect in Graphene by Electric Field
Shengli Zhang, Ning Ma, Erhu Zhang
This paper is to explore the de Haas-van Alphen effect of graphene in the presence of an in-plane uniform electric field. Three major findings are yielded. First of all, t…
Quantum transport in a curved one-dimensional quantum wire with spin-orbit interactions
Erhu Zhang, Shengli Zhang, Qi Wang
The one-dimensional effective Hamiltonian for a planar curvilinear quantum wire with arbitrary shape is proposed in the presence of the Rashba spin-orbit interaction. Single electr…
Anomalous Valley Magnetic Moment of Graphene
Daqing Liu, Shengli Zhang, Erhu Zhang +2
Carrier interactions on graphene are studied. The study shows that besides the well known Coulomb repulsion between carriers, there also exist four-fermion interactions associated…
