Optical study of Dirac fermions and related phonon anomalies in antiferromagnetic compound CaFeAsF
B. Xu, H. Xiao, B. Gao +8
We performed optical studies on CaFeAsF single crystals, a parent compound of the 1111-type iron-based superconductors that undergoes a structural phase transition from tetragonal…
Possible structural origin of superconductivity in Sr-doped Bi2Se3
Zhuojun Li, Meng Wang, Dejiong Zhang +13
Doping bismuth selenide (Bi2Se3) with elements such as copper and strontium (Sr) can induce superconductivity, making the doped materials interesting candidates to explore potentia…
Strong anisotropy effect in iron-based superconductor CaFeCoAsF
Yonghui Ma, Qiucheng Ji, Kangkang Hu +4
The anisotropy of the Fe-based superconductors is much smaller than that of the cuprates and the theoretical calculations. A credible understanding for this experimental fact is st…
Growth and characterization of CaFeCoAsF single crystals by CaAs flux method
Yonghui Ma, Kangkang Hu, Qiucheng Ji +5
