Topological phase transition induced by magnetic proximity effect in two dimensions
Yijie Zeng, Luyang Wang, Song Li +3
We study the magnetic proximity effect on a two-dimensional topological insulator in a CrI/SnI/CrI trilayer structure. From first-principles calculations, the BiI-t…
Work function of α-Fe_{2}O_{3} : a DFT calculation
Chunshan He
The work functions of (001) and (00 -1) surfaces of α-Fe_{2}O_{3} are investigated with density functional theory and symmetry slab model. These two surfaces are found to be almost…
Stabilities and novel electronic structures of three carbon nitride bilayers
Wanxing Lin, Shi-Dong Liang, Chunshan He +5
Three new novel phases of carbon nitride (CN) bilayer, which are named as α-CN, β-CN and γ-CN, respectively, have been predicted in this paper.…
Screening effects on field emission from arrays of (5,5) carbon nanotubes: Quantum-mechanical simulation
Guihua Chen, Weiliang Wang, Jie Peng +4
The simulation of field electron emission from arrays of micrometer-long open-ended (5, 5) carbon nanotubes is performed in the framework of quantum theory of many electrons. It is…
The roles of apex dipoles and field penetration in the physics of charged, field emitting, single-walled carbon nanotubes
Jie Peng, Zhibing Li, Chunshan He +8
A 1 m long, field emitting, (5,5) single-walled, carbon nanotube (SWCNT) closed with a fullerene cap, and a similar open nanotube with hydrogen-atom termination, have been simul…
Atomic decoration for improving the efficiency of field electron emission of carbon nanotubes
Guihua Chen, Zhibing Li, Jie Peng +9
The field electron emission from the single-walled carbon nanotubes with their open ends terminated by -BH, -NH, and -O has been simulated. The apex-vacuum barrier and the emission…
