Giant biquadratic interaction induced magnetic anisotropy in the iron-based superconductor AxFe2-ySe2
Hai-Feng Zhu, Hai-Yuan Cao, Yun Xie +4
The emergence of the electron-pocket only iron-based superconductor AxFe2-ySe2 (A = alkali metal) challenges the Fermi-surface nesting picture established in iron-pnictides. It was…
Oxygen Vacancy Induced Flat Phonon Mode at FeSe /SrTiO3 interface
Yun Xie, Hai-Yuan Cao, Yang Zhou +3
A high-frequency optical phonon mode of SrTiO3 (STO) was found to assist the high-temperature superconductivity observed recently at the interface between monolayer FeSe and STO su…
Antiferromagnetic ground state with pair-checkboard order in FeSe
Hai-Yuan Cao, Shiyou Chen, Hongjun Xiang +1
Monolayer FeSe thin film grown on SrTiO_{3}(001) (STO) shows the sign of T_{c}> 77 K, which is higher than the T_{c}-record of 56 K for the bulk FeAs-based superconductors. However…
The interfacial effects on the spin density wave in FeSe/SrTiO3 thin film
Hai-Yuan Cao, Shiyong Tan, Hongjun Xiang +2
Recently, the signs of both superconducting transition temperature (Tc) beyond 60 K and spin density wave (SDW) have been observed in FeSe thin film on SrTiO3 (STO) substrate, whic…
What Is Armchair-Zigzag Grain Boundary Structure in Graphene?
Zheng-Lu Li, Hai-Yuan Cao, Ji-Hui Yang +4
We have developed a new global optimization method for the determination of interface structure based on the differential evolution algorithm. Here, we applied this method to searc…
Unexpected large thermal rectification in asymmetric grain boundary of graphene
Hai-Yuan Cao, Hongjun Xiang, Xin-Gao Gong
We have investigated the lattice thermal transport across the asymmetric tilt grain boundary between armchair and zigzag graphene by nonequilibrium molecular dynamics (NEMD). We ha…
Layer and size dependence of thermal conductivity in multilayer graphene nanoribbons
Hai-Yuan Cao, Zhi-Xin Guo, Hongjun Xiang +1
Using non-equilibrium molecular dynamics method(NEMD), we have found that the thermal conductivity of multilayer graphene nanoribbons monotonously decreases with the increase of th…
