TEM images of FeP. (a) Low-magnification image of FeP nanobundles. (b) High-magnification image of FeP reveals that the nanobundles are polycrystalline. (c) An image of an individual branch of FeP. (d) Lattice fringes indicate a lattice spacing of d002 = 0.29 nm consistent with the orthorhombic phase of FeP.
