Evidences for the exciton gas phase and its condensation in monolayer 1T-ZrTe2
Yekai Song, Chunjing Jia, Hongyu Xiong +15
The excitonic insulator (EI) is a Bose-Einstein condensation (BEC) of excitons bound by electron-hole interaction in a solid, which could support high-temperature BEC transition. T…
Epitaxial growth and characterization of high quality Bi2O2Se thin films on SrTiO3 substrates by pulsed laser deposition
Yekai Song, Zhuojun Li, Hui Li +8
Recently, Bi2O2Se is discovered as a promising two-dimensional (2D) semiconductor for next generation electronics, due to its moderate bandgap size, high electron mobility and pron…
Two-Gap Superconductivity in CaFe_{0.88}Co_{0.12}AsF Revealed by Temperature Dependence of the Lower Critical Field H_{c1}^c(T)
Teng Wang, Yonghui Ma, Wei Li +8
Gap symmetry and structure are crucial issues in understanding the superconducting mechanism of unconventional superconductors. Here we report an in-depth investigation on the out-…
Single-crystal growth and extremely high H_c2 of 12442-type Fe-based superconductor KCa_2Fe_4As_4F_2
Teng Wang, Jianan Chu, Hua Jin +11
Millimeter sized single crystals of KCa_2Fe_4As_4F_2 were grown using a self-flux method. The chemical compositions and crystal structure were characterized carefully. Superconduct…
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…
A combined method for synthesis of superconducting Cu doped Bi2Se3
Meng Wang, Yanru Song, Lixing You +4
We present a two-step technique for the synthesis of superconducting CuxBi2Se3. Cu0.15Bi2Se3 single crystals were synthesized using the melt-growth method. Although these samples a…
