FeSe layer-based superconductors exhibit exotic and distinctive properties. The undoped shows nematicity superconductivity, while the heavily electron-doped KxFe2-ySe2 single-layer FeSe/SrTiO3 possess high superconducting transition temperatures that pose theoretical challenges. However, a comprehensive study on doping dependence of an superconductor is still lacking due to lack clean means control. Through angle-resolved photoemission spectroscopy studies K-dosed thick films FeSe0.93S0.07...
Abstract Cough is a common symptom of various respiratory diseases. However, recognizing subject's cough using acoustic imaging can be challenging due to the complexity coughing and vulnerability acquisition external interference. This research aims address these issues by utilizing flexible piezoelectric ionic liquid‐doped poly(L‐lactic acid) (PLLA) sensor gather pressure signals from human surface. 1‐butyl‐3‐methylimidazolium bis (trifluoromethylsulfonyl)imide ([BMIm]TFSI) liquid (IL)...
A comprehensive study of the doping dependence phase diagram FeSe-based superconductors is still required due to lack a clean and systematic means control. Here, we report on magneto-optical imaging, thermodynamic transport properties, as well in situ angle-resolved photoemission spectroscopy (ARPES) studies impurity scattering stoichiometric FeSe single crystals. Co at Fe site found decrease superconducting transition temperature $({T}_{c})$. The upper critical field specific heat all...
This article uses innovative UV-curable acrylate elastomer with AgNWs to develop flexible strain sensors for wrist movement monitoring.
To understand the high temperature superconductivity at 65 K in single-layer FeSe films grown on Nb:SrTiO3 substrates, one crucial issue is to distinguish effects of different interfacial interactions. In this paper, we decouple effect tensile strain with those other interactions, and studying corresponding electronic structure superconducting gap behavior through in-situ angle resolved photoemission spectroscopy. By growing FeSe/Nb:SrTiO3/LaAlO3 heterostructures varied thicknesses films,...
Iron chalcogenide superconductors are multi-band systems with strong electron correlations. Here we use angle-resolved photoemission spectroscopy to study band dependent correlation effects in single-layer FeSe/Nb:BaTiO3/KTaO3, a new iron superconductor non-degenerate pockets and interface-enhanced superconductivity. The non-degeneracy of the bands helps resolve temperature evolution different bands. With increasing temperature, single layer FeSe undergoes band-selective localization, which...
LaO(0.5)F(0.5)BiSe(2) is a new layered superconductor discovered recently, which shows the superconducting transition temperature of 3.5 K. With angle-resolved photoemission spectroscopy, we study electronic structure comprehensively. Two electron-like bands are located around X point Brillouin zone, and outer pockets connect with each other form large Fermi surface Γ M. These show negligible k(z) dispersion, indicating their two-dimensional nature. Based on Luttinger theorem, carrier...
