WebCrystals of FeSe 0.88 and FeSeMn 0.1 have been grown from KCl solutions. Crystals measuring 2−3 mm across and 0.1−0.3 mm thick grow with a hexagonal plate like habit. Powder X-ray diffraction (XRD) measurements show strong peaks corresponding to the tetragonal α-FeSe phase and weak hexagonal β-FeSe peaks in both cases. WebSep 4, 2024 · Temperature-dependent electrical transport demonstrates that the FeTe 2 nanoflake is a semiconductor with a variable range hopping (VRH) conduction, and its …
One-step synthesis of FeSe0.45Te0.55 single crystals without …
WebCrystallization, Abstract A new approach to grow FeSe 1−x Te x single crystals with an optical zone-melting technique was successfully employed. Crystals with actual composition 0.4 ≤ x ≤ 1.0 all show high crystallinity with no phase separation. WebOct 1, 2012 · The NaFeAs and α-FeTe single crystals were synthesized following previous reports. 8,16 There are ∼ 8.8 % excess Fe in FeTe based on our energy-dispersive x-ray spectroscopy lowes 3810039
Phase-controllable growth of ultrathin 2D magnetic FeTe
WebWe performed INS measurements on a FeTe Se single crystal in order to study the dependence of the Q spectra from = (0,0) to (, ), including ( ,0). Good statistics are required to measure the -dependent enhancement and to … WebApr 26, 2024 · Excess interstitial Fe atoms in as-grown FeSe 1−x Te x single crystals are unavoidable in the self-flux growing procedure. As harmful defects to the study of superconductivity and Majorana fermions, the excess Fe atoms are usually removed by the post-annealing procedure. WebAug 25, 2024 · FeTe single crystal was grown by the vertical Bridgman method. High-purity Fe (99.999%) and tellurium (99.99999%) powders were loaded into a carbon-coated quartz tube, and the quartz tube was sealed under a pressure of < 10 –6 torr. The ampoule was held at 1000 °C for 24 h inside a vertical furnace and lowered the position slowly at a rate ... horry county schools pay scales
