Light-matter interaction is not only used to melt electronic orders, but also carry the potential as a non-thermal tuning knob to enhance emergent orders. Here the authors demonstrate a light-induced transient enhancement of superconductivity in an i

Illumination of light on matter normally causes heating and destroys the ordered ground states. Despite this common understanding, recent advances in ultrafast light sources have enabled the non-thermal control of quantum phases. Here, we report the

We measured the complex conductivity, $\ensuremath{\sigma}$, of $\mathrm{Fe}{\mathrm{Se}}_{1\ensuremath{-}x}{\mathrm{Te}}_{x}$ $(x=0\ensuremath{-}0.5)$ films in the superconducting state which show a drastic increase of the superconducting transition

Muon spin rotation/relaxation measurements were performed to investigate magnetic properties of $\mathrm{Fe}{\mathrm{Se}}_{1\ensuremath{-}x}{\mathrm{S}}_{x}$ thin films on $\mathrm{La}\mathrm{Al}{\mathrm{O}}_{3}$. A drastic decrease of the initial as
We investigated chemical pressure effects in electron-doped (e-doped) FeSe by fabricating an electric-double-layer structure with single crystalline FeSe films on LaAlO$_3$ with Se substituted by isovalent Te and S. Our method enables transport measu

The authors use angle-resolved photoemission spectroscopy to show distinct electronic structures with different orbital characters between pristine FeSe and high-$T$${}_{c}$ FeSe${}_{1\ensuremath{-}x}$Te${}_{x}$ superconductors.

In this study, we investigated the gate voltage dependence of $T_{\mathrm c}$ in electrochemically etched FeSe films with an electric-double layer transistor structure. The $T_{\mathrm c}^{\mathrm {zero}}$ value of the etched FeSe films with a lower

We investigated chemical pressure effect of the electron-doped FeSe1−x S x and FeSe1−y Te y on LaAlO3 (x ≤ 0.25, y ≤ 0.5) with the electric double layer transistor structure. T c of all the FeSe1−x S x and FeSe1−y Te y films except y = 0.

Exploration of new superconductors still relies on the experience and intuition of experts and is largely a process of experimental trial and error. In one study, only 3% of the candidate materials showed superconductivity. Here, we report the first
