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...

Dec 2, 2014 · By characterizing the structural and superconducting properties for the full range of FeSe x Te 1-x thin films, for the first time, we were able to construct the complete phase diagram.

Apr 21, 2017 · Figure 1a shows the X-ray diffraction (XRD) patterns of the FeSe 1−x Te x thin films with x = 0–0.5 fabricated on LAO substrates. Here and hereafter, the Te content x of the film represents the...

The crystalline product was revealed by X-ray diffraction (XRD), while the morphology consisted of polygonal crystallites according to the scanning electron microscopy (SEM) studies.

X-ray diffraction (XRD) patterns of those FeSe films reveal the structural modification with DC power of Fe source and substrate conditions. The film synthesized at 10 W with 30 min deposition time shows Fe 7 Se 8 phase and Fe particles with a negligible β -FeSe signal, while a longer deposition time of 2 h allows the formation of β -FeSe ...

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.

Jun 1, 2006 · X-ray powder diffraction (XRD) patterns were recorded on a Japan Rigaku D/max-γB X-ray diffractometer with Cu Kα radiation (λ =1.54187 Å). Transmission electron microscopy (TEM) images were obtained on a Hitachi H-800 transmission electron microscope with an accelerating voltage of 200 kV.

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

X-ray diffraction (XRD) data and analysis for epitaxial iron selenide thin films grown by pulsed laser deposition (PLD) are presented to support the conclusions in the related research article “Double epitaxy of tetragonal and hexagonal phases in the FeSe system” [1].

Mar 9, 2022 · According to the XRD pattern, the crystal samples consist of dominant tetragonal β -FeSe phase and trace amount of hexagonal δ -FeSe phase. The superconducting transition temperature of FeSe 0.94 is determined to be around 9.5 K based on the magnetization and electronic transport measurements.
