| 中文摘要 | An iron-selenide Na0.8Fe1.6Se2 single crystal has been successfully synthesized using a self-flux method. The electrical resistivity measurement shows that this material exhibits semiconducting behavior in the whole temperature range, with an anomalous increment of resistivity at T-s similar to 595 K. By varying the concentrations of Na and Fe, a small volume of superconducting phase could be achieved with a critical temperature of T-c similar to 34 K. Structural characterization shows that, similarly to K0.8Fe1.6Se2, the Na0.8Fe1.6Se2 phase exhibits clear superstructure with a modulation wave vector of q = (3/5,1/5,0) caused by the Fe-vacancy order within the a-b plane. |
