(a) SEM image of NixFe1−xSe2 nanoplates. (b) Magnified SEM image showing the nanoparticles grown on the nanoplates. (c) TEM image of a nanoparticle. (d) Magnified TEM image showing the nanosheets that make up the nanoparticles. (e) HRTEM image of a nanosheet. The inset shows the FFT image of (e). Scale bars: (a) 10 μm; (b) 1 μm; (c) 50 nm; (d) 20 nm; and (e) 2 nm. FFT, fast-Fourier transform.
