Abstract:

2D Fe-chalcogenides have drawn significant attention due to their unique structural phases and distinct properties in exploring magnetism and superconductivity. However, it remains a significant challenge to synthesize 2D Fe-chalcogenides with specific phases in a controllable manner since Fe-chalcogenides have multiple phases. Herein, a molecular sieve-assisted strategy is reported for synthesizing ultrathin 2D iron sulfide on substrates via the chemical vapor deposition method. Using a molecular sieve and tuning growth temperatures to control the partial pressures of precursor concentrations, hexagonal FeS, tetragonal FeS, and non-stoichiometric Fe7S8 nanoflakes can be precisely synthesized. The 2D h-FeS, t-FeS, and Fe7S8 have high conductivities of 5.4 x 10(5) S m(-1), 5.8 x 10(5) S m(-1), and 1.9 x 10(6) S m(-1). 2D tetragonal FeS shows a superconducting transition at 4 K. The spin reorientation at approximate to 30 K on the non-stoichiometric Fe7S8 nanoflakes with ferrimagnetism up to room temperature has also been observed. The controllable synthesis of various phases of 2D iron sulfide may provide a route for synthesizing other 2D compounds with various phases.
