We prepare single-unit-cell FeSe films on insulating SrTiO3 substrates by molecular beam epitaxy and investigate the evolution of their superconducting properties with annealing by in situ scanning tunneling microscopy and scanning tunneling spectroscopy and ex situ transport measurements. We find t...

We prepare single-layer potassium-doped iron selenide (110) film by molecular-beam expitaxy. Such a single-layer film can be viewed as a two-dimensional system composed of weakly coupled two-leg iron ladders. Scanning tunneling spectroscopy reveals that superconductivity is developed in this two-leg...

We present research on the superconducting properties of Nb_xRe_1−x (x=0.13–0.38) obtained by measuring the electrical resistivity ρ(T), magnetic susceptibility χ(T), specific heat C_P(T), and London penetration depth Δλ(T). It is found that the superconducting transition temperature T_c decreases monot...
