“…The two peaks at 710.69 and 724.06 eV correspond to the Fe 2p 1/2 and Fe 2p 3/2 binding energies, [18][19][20] respectively. The Se 3d peak of FeSe 2 microflowers is located at 55.4 eV, which is consistent with FeSe 2 bulk materials.…”

“…18 Gao et al 19 reported the synthesis of Fe 7 Se 8 polyhedra and Fe 7 Se 8 nanorods in diethylenetriamine (DETA) and deionized water (DIW). Nanorods of iron selenide (FeSe 2 ) also have been synthesized by the hydrothermal coreduction method using N 2 H 4 $H 2 O as the reductant.…”

Iron selenide nanocrystals (NCs) were synthesised by the thermolysis of single molecular precursors, bis(tetraisopropyldiselenoimidodiphosphinato)iron(II) (3) and bis(tetraphenyldiselenoimidodiphosphinato) iron(II) (4) in oleylamine and hexadecylamine at different growth temperatures. TEM images of the NCs showed the rod and plate-like crystallites. Both complexes were also used for the deposition of thin films by Aerosol Assisted Chemical Vapour Deposition (AACVD) onto silicon substrates. SEM images of thin films deposited from complex (3) and (4) showed significantly different morphologies under similar conditions. X-ray single crystal structures of complexes [Fe{(SePPh 2 ) 2 N} 2 ] (4) and [(SePPh 2 ) 2 N)-O-(SePPh 2 ) 2 N)] (5) were also determined.

“…FeSe comes in several phases: (a) a tetragonal phase -FeSe with PbO-structure, (b) a NiAs-type -phase with a wide range of homogeneity showing a transformation from hexagonal to monoclinic symmetry, and (c) a FeSe phase that has the orthorhombic marcasite structure. The most studied of these compounds are the hexagonal Fe Se phase, which is a ferrimagnet with Curie temperature at around 250 K [12], [13] and monoclinic Fe Se . Iron chalcogenides are low career density metals with high density of states where the electronic structure near the Fermi level is mainly influenced by Fe derived bands.…”

We report the effect of 3d metal Cobalt (Co) and Nickel (Ni) doping on the FeTe Se superconductor with the nominal composition range Fe M Te Se ( and , and 0.10). Samples are synthesized through standard solid state reaction route and all are crystallize in single phase tetragonal structure with space group P4/nmm. The lattice parameters ' ', ' ' and volume decrease with increase in Co and Ni content, although not monotonically. In fact the ' ' lattice parameter is nearly unaffected for Co doped samples. The superconducting transition temperature is measured from both DC and AC magnetic susceptibility, which decrease with increase in Ni or Co content. Both Co and Ni suppress and drive the system into the normal state. Interestingly, Ni suppresses the superconductivity much faster than the Co. This indicates less effect on in-plane Fe-Se distances and thus reduced disorder in case of Co when compared with Ni substation at Fe site in FeTe Se superconductor. It is concluded that in-plane disorder on superconducting Fe-Se and Fe-Se-Se planes directly affects superconductivity in FeTe Se superconductor.
