Flower-like tetragonal iron selenide (β-FeSe) microstructures assembled from nanoplates have been successfully prepared using Se powder and FeCl3·6H2O as elemental precursors in the basic...

Jan 15, 2021 · We are able to obtain a series of single crystals of FeSe 1−x Te x up to x (Te) ~ 0.5. Figure 1 a–c shows the results of X-ray diffraction (XRD) analysis at room temperature.

FeSe is lead oxide structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one FeSe sheet oriented in the (0, 0, 1) direction.

FeSe2 particles were facilely synthesized through a simple solvothermal reduction reaction in air. By using iron nitrate and selenide as raw materials, and oleylamine as solvent, 96% yield of the...

Dec 2, 2014 · Here, thin FeSe x Te 1-x films with the Se content covering the full range (0 ≤ x ≤ 1) were fabricated by using pulsed laser deposition method. Crystal structure analysis shows that all films...

Dec 15, 2024 · In this study we successfully grown FeSe 0.84 S 0.1 single crystals using the high-temperature KCl flux method and reported the effect of S-doping on crystal structure and superconducting characteristics in FeSe 0.94.

This review introduces the crystal structures and superconducting properties of several typical FeSe-based superconductors containing ammonia/organic molecules intercalation discovered in...

Jan 24, 2020 · To characterize the crystal structure, the θ –2 θ, azimuthal phi, and rocking curve were measured using a four-circle XRD (PANalytical, X’Pert pro, λ = 1.5406 Å).

Dec 12, 2013 · A new crystal structure with tetrahedral FeSe 2 chains was synthesized from the simplest starting materials, elemental Fe and Se. Fe 3 Se 4 (en) 2 exhibits antiferromagnetic ordering within the tetrahedral chains.

Apr 26, 2022 · Phase purity and crystal quality were examined by single crystal x-ray diffraction (XRD) performed at room temperature. The single crystal XRD patterns were collected using a PANalytical Empyrean S3 with Cu-Kα1 radiation.
